AB  - U okviru ove doktorske disertacije je ispitan uticaj koncentracije dopanta na svojstva BaCe1−xInxO3–δ (BCI, x = 0,05; 0,10; 0,15; 0,20; 0,25; 0,30; 0,35 i 0,40) kao protonskog provodnika. Struktura i fazni sastav sintetisanih prahova dobijenih metodom samosagorevanja su utvrđeni rendgenskom difrakcionom analizom, pri čemu je pokazano da prahovi sa ≥ 25 % (mol.) indijuma sadrže In2O3 kao sekundarnu fazu. Optimizacijom postupka sinterovanja je utvrđeno da je termički tretman na 1300 °C tokom 5 h optimalan za dobijanje guste neporozne keramike (98 % teorijske vrednosti). Mikrostruktura je analizirana skanirajućom elektronskom mikroskopijom (SEM). Povećanje temperature sinterovanja dovodi do nastanka većih zrna, dok povećanje koncentracije indijuma do 25 % (mol.) dovodi do porasta zrna, a iznad te koncentracije nema daljeg uticaja na veličinu zrna. Izlaganjem sinterovanog uzorka atmosferi CO2 tokom 5 h na 700 °C je pokazano da indijum u potpunosti suzbija degradaciju BaCeO3 već u koncentraciji od 15 % (mol.). Električnim merenjima u atmosferi vlažnog vodonika je utvrđeno da maksimalna ukupna provodljivost iznosi 5 × 10−3 S cm–1 na 700 °C za uzorak BaCe0,75In0,25O3–δ (BCI25), zbog čega je ovaj materijal odabran kao najbolji kandidat za elektrolit gorivne ćelije na bazi oksida u čvrstom stanju. Dobijena gorivna ćelija Ni-BaCe0,75In0,25O3−δ║BaCe0,75In0,25O3−δ║LSCF-BaCe0,75In0,25O3−δ (LSCF = lantan-stroncijum-kobalt-gvožđe-oksid, La0,8Sr0,2Co0,8Fe0,2O3) je pokazala maksimalnu gustinu izlazne snage od 264 mW cm–2 na 700 °C, koristeći vlažan vodonik kao gorivo. Ovakav rezultat ukazuje na stabilnost i funkcionalnost BCI25 kao elektrolita za gorivne ćelije.
Ispitivanjem električnih svojstava BCI25 u atmosferama različitog sastava je uočeno da dolazi do brze promene impedanse prilikom promene parcijalnog pritiska vodene pare, što čini ovaj materijal pogodnim za primenu kao visokotemperaturnog senzora vodene pare. Senzorska svojstva BCI25 u vidu poroznog filma i sinterovane keramike su ispitana u temperaturnom opsegu 250 °C – 700 °C. Film debljine 30 μm, napravljen od praha kalcinisanog na 1050 °C, je pokazao osetljivost uporedivu sa osetljivošću sinterovanog uzorka, ali sa značajno kraćim vremenom odziva i oporavka. Pokazalo se da je najbolja osetljivost senzora na temperaturi od 500 °C. Osetljivost filma se postepeno smanjivala sa smanjenjem parcijalnog pritiska vodene pare pH2O, ali je bila značajna i pri parcijalnom pritisku vodene pare od 200 Pa. Pad provodljivosti je zavisio logaritamski od parcijalnog pritiska vodene pare sa nagibom od 0,52 što je blisko tipičnoj vrednosti za protonski tip provođenja u tom temperaturnom opsegu. Posle nekoliko ciklusa, test ponovne upotrebe je pokazao skoro nepromenjen odnos između impedanse u suvoj i vlažnoj atmosferi (pH2O = 2,34 kPa), što je ukazalo na dobru stabilnost i osetljivost BCI25 kao potencijalnog visokotemperaturnog senzora vodene pare.

AB  - Systematic analysis of electrical characteristics of BaCe0.75In0.25O3-δ (BCI25) sintered sample was performed in a
dry and a wet argon atmosphere in the 250 ◦C–700 ◦C temperature range. The water vapor sensing properties of
BCI25 porous film and its response and recovery times were investigated under different conditions of temperature
and water vapor concentration. The 30 μm thick film obtained from the powder calcined at 1050 ◦C
exhibited sensitivity comparable to that of the sintered sample with a significantly shorter response and recovery
times. While the sensitivity of the film gradually decreased with a decrease in partial pressure of water vapor (p
(H2O)), a noticeable sensitivity was still observed at p(H2O) of 200 Pa. Decrease in conductivity depended
logarithmically on the partial pressure of water with the slope of 0.52 that is close to the theoretical value. After
several cycles, the reusability test proved an almost unchanged ratio between the impedance value in the dry and
the wet Ar atmosphere (p(H2O) = 2.34 kPa), which implied that BCI25, having good stability and sensitivity, is a
promising high-temperature humidity sensor.

AB  - Numerous methods have been utilized for molecular detection, including optical, calorimetric, acoustic, and techniques based on changes in electrical properties, such as metal oxide semiconductor sensors [1,2]. Recent research endeavors have led to a significant rise in sensitivity, detecting parts per billion (ppb) [3], but the challenges of selectivity and cross-sensing remain crucial areas of investigation. Developing a gas sensor with high selectivity to efficiently analyze multi-gas mixtures would be of great significance, with potential applications in various fields such as technology, environmental control, biology, and medicine.
Quantum sensors are a promising new technology for the detection of gas mixtures. They offer a number of advantages over traditional methods, including high sensitivity, selectivity, and response time. In the presentation, we propose a new method based on the resonant interaction of dipole molecules with ac fields, in the presence of a dc electric and magnetic field that creates Zeeman and Stark splitting of molecular levels specific to certain molecules, ensuring selectivity [4].
In this talk, we present some preliminary experimental results obtained for the molecule NO on the use of quantum sensors for the detection of gas mixtures. Our results demonstrate the potential of quantum sensors for a variety of applications in gas sensing. We believe that quantum sensors have the potential to revolutionize the field of gas sensing.

AB  - Barium-stannate (BaSnO3, BSO) is a member of the perovskite-type alkaline
earth stannates ASnO3 (A = Ca, Sr, Ba) with an ideal cubic crystal structure (space
group: ). Doping with antimony (Sb5+) can change this wide band-gap
semiconductor (Eg = 3.1-3.4 eV) into an n-type semiconductor with high electrical
conductivity at room temperature. The major drawbacks in the BSO-based ceramics
synthesis are phase composition and low density of final ceramic materials. These
problems could be solved using spark plasma sintering (SPS), a current and
pressure-assisted technique, which enables the preparation of dense ceramics at
significantly lower temperatures and for a shorter time.
To investigate the influence of spark plasma sintering temperature on the
structural, microstructural and electrical properties of BaSn1-xSbxO3 (BSSO, x =
0.00; 0,04; 0.06; 0.08; and 0.10) ceramics samples, BSSO powders were spark
plasma sintered at 1100 °C, 1200 °C and 1250 °C for 5 min.
X-ray diffraction (XRD) analysis confirmed that all ceramic samples sintered at
1100 °C crystallized in a single-phased cubic BSO structure. Their relative densities
were in the range of 72–82% ρt. Sintering at 1200 °C increased the samples’ relative
densities to 79–96% ρt, but also induced the formation of a barium-rich secondary
phase, Ba2SnO4. Rising the sintering temperature further to 1250 °C induced the
melting of all samples except BaSn0.92Sb0.08O3. Field emission scanning electron
microscopy (FE-SEM) revealed that doping with antimony decreased the grain sizes
in BSSO samples sintered at 1100 °C and 1200 °C up to the concentration x = 0.08.
Electrical measurements revealed the typical semiconductor behavior of the
undoped samples, showing nonlinear current-voltage characteristic and the existence
of one semicircle in their impedance spectra, characteristic for materials with double
Schottky barrier at the grain boundaries. However, samples with higher dopant
concentrations (x = 0.08 and 0.10) showed significantly lower electrical resistivity
and linear current-voltage characteristic. The lowest and almost constant value of
electrical resistivity in the temperature range of 25–150 °C, and complete loss of the
semicircle in its impedance spectrum revealed the metallic-like behavior of sample
BaSn0.92Sb0.08O3 sintered at 1200 °C.

AB  - The non-magnetic, non-inductive electroconductive materials with linear current-voltage characteristic and low and almost constant electrical resistivity in the wide temperature range could be used in conditions unfavorable for metals and alloys. Particular emphasis is placed on the performance and endurance of these materials in conditions at constant high voltage, current, and energy, as well as operating in acidic and humid environmental conditions.
The aim of this work was to investigate the influence of antimony concentration and sintering parameters on the structure, microstructure, and electrical properties of antimony-doped barium stannate, BaSn1-xSbxO3 (BSSO, x = 0,00; 0,04; 0,06; 0,08 and 0,10) to obtain conductive electroceramic samples with linear current-voltage (I- U) characteristics and low electrical resistivity. For this purpose three different sintering techniques were used: conventional, spark plasma and cold sintering.
According to the X-ray diffraction (XRD) analysis, single-phase ceramic mater- ials with cubic BaSnO3 structure were obtained by conventional sintering at 1600 °C for 3 h and spark plasma sintering at 1100 °C for 5 min. Raising the spark plasma sintering temperature to 1200 °C induced the formation of Ba-rich secondary phase, Ba2SnO4. XRD analysis confirmed the presence of unreacted SnO2 and BaCO3 in cold sintered BaSn0.92Sb0.08O3 sample (310 °C for 5 min, 20 wt.% 1 M acetic acid). Scanning electron microscopy (SEM) indicates a significant decrease in grain size upon doping, regardless of the sintering technique. High-resolution transmission electron microscopy (HRTEM) revealed the presence of low angle grain boundaries (LAGBs) in conventionally and spark plasma sintered (1200 °C for 5 min) samples with x = 0.08. The results of electrical measurements confirmed the semiconducting properties of all BSSO, except the spark plasma sintered BaSn0.92Sb0.08O3 (1200 °C for 5 min) sample. This sample showed linear current-voltage characteristic, the lowest and almost constant electrical resistivity in the temperature range of 25–150
°C resulting from the loss of potential barriers at grain boundaries due to the large fraction of LAGBs present in BaSn0.92Sb0.08O3 ceramic sample.

AB  - Acceptor-doped perovskites (ABO3 general formula) with large lattice constants (such as BaCeO3, SrCeO3, and BaZrO3) have been known as fast proton conductors. The ability to conduct protons at high temperatures makes them suitable for humidity sensors in a high-temperature environment. The presence of traces of humidity can play a key role in the functioning of certain industrial processes at higher temperatures. Electrical characteristics of BaCe0.75In0.25O3–δ (BCI25) sintered sample were analyzed in a dry and a wet argon atmosphere in the 250–700 °C temperature range. The water vapor sensing properties of BCI25 porous film and its response and recovery times were investigated under different conditions of temperature and water vapor concentration. A 30 μm thick film obtained from the powder calcined at 1050 °C exhibited sensitivity comparable to that of the sintered sample with significantly shorter response and recovery times. While the sensitivity of the film gradually decreased with a decrease in partial pressure of water vapor (p(H2O)), a noticeable sensitivity was still observed at p(H2O) of 200 Pa. Decrease in conductivity depended logarithmically on the partial pressure of water with the slope of 0.52 that is close to the theoretical value. After several cycles, the reusability test proved an almost unchanged ratio between the impedance value in the dry and the wet Ar atmosphere (p(H2O) = 2.34 kPa), which implied that BCI25, having good stability and sensitivity, is a promising high-temperature humidity sensor.

AB  - Mixed oxides with the perovskite structure are known for their proton conducting ability at the temperatures above 500 °C. This characteristic makes them suitable for application as an electrolyte for intermediate-temperature solid oxide fuel cells. Doping of BaCeO3 with In3+ in place of Ce4+ leads to emergence of oxygen vacancies which take part in creation of proton defects. The characteristics of the BaCe1-xInxO3-δ were investigated in a wide range of In dopant concentrations (x = 0.05; 0.10; 0.15; 0.20; 0.25; 0.30; 0.35 and 0.40). All the samples were synthesized by a citric-nitric autocombustion method. The dense electrolytes were formed after sintering at 1300 °C for 5 h in air. X-ray powder diffraction analysis showed that powders with In content greater than 25 mol% contained In2O3 as a secondary phase. The highest total conductivity around 5×10–3 S•cm–1 was measured for the sample BaCe0.75In0.25O3-δ in the wet hydrogen atmosphere at 700 °C. After exposure to pure CO2 atmosphere at 700 °C for 5 h, the samples were investigated by X-ray diffraction analysis. It was found that even 15 mol% In could completely suppress degradation of the electrolyte. Ni-
BaCe0.75In0.25O3-δ/BaCe0.75In0.25O3-δ/LSCF-BaCe0.75In0.25O3-δ fuel cell was tested in wet hydrogen atmosphere and power density output of 264 mW•cm–2 was measured at 700 °C. This result is an indication of stability and functionality of this electrolyte and its versatility in respect to type of fuel and performing environment.

AB  - Barium stannate, BaSnO3 (BSO), a cubic perovskite-type oxide with its
interesting structural, optical and electrical properties has wide application as an
electrode material, thermally stable capacitor, transparent conductive oxide,
photocatalyst, humidity and gas sensor material [1]. Partial substitution of Sn by Sb
in BSO leads to drastic changes primarily in its electrical properties, resulting in
metallic-like conductivity of doped ceramics. Major problems concerning the
synthesis of Sb doped BSO (BSSO) are connected to the phase composition and
density of final ceramic material.
This study covers the comprehensive investigation of structural, microstructural
and electrical properties of the Sb-doped BaSn1-xSbxO3 (x = 0.00, 0.04 and 0.08,
BSSO) ceramic materials obtained by two different sintering techniques:
conventional sintering (CS) and Spark Plasma sintering (SPS). The relative densities
of the BSSO-CS ceramic samples sintered at 1600 °C for 3 h was in the range of 79–
96 %. On the other side, the relative densities of BSSO-SPS ceramic samples in the
range of 86–96 % were obtained at 1200 °C, with sintering time of only 5 minutes.
The XRD analysis confirmed that cubic BaSnO3 is a major phase in all BSSO
samples. The presence of tetragonal Ba2SnO4 as a secondary phase was detected in
BSSO-SPS ceramic samples, with its content decreasing upon Sb-doping. As
expected, the grain size of the samples sintered at higher temperatures (BSSO-CS) is
larger in comparison with BSSO-SPS ceramic samples, which was confirmed by
Scanning Electron Microscopy (SEM). SEM analysis also revealed the layered
structure within the grains of BaSn0.92Sb0.08O3-CS sample while HRTEM analysis
confirmed the existence of the low angle grain boundaries (LAGBs) in the SPSed
sample with the same composition.
The electrical resistivity decreased upon Sb doping, and all doped BSSO
samples showed the linear I-U characteristic in the temperature range of 25–150 °C.
The semiconductor behavior of all BSSO-CS and BSSO-SPS (x = 0.00 and 0.04)
ceramic samples was confirmed through the existence of semicircles in their
impedance spectra. On the other hand, the BaSn0.92Sb0.08O3 sample showed the
metallic-like behavior resulting from the loss of the electrostatic barriers at LAGBs,
which is manifested through the absence of the semicircle in its impedance spectra.

AB  - Regarding limited fossil energy resources and
hence the increasing demands for new highly efficient
and environmentally friendly energy conversion
devices, the widespread use of solid oxide fuel cells
(SOFCs) might become a keystone in near future. An
SOFC is consisted of dense electrolyte which is
sandwiched between two porous electrodes. Since the
electrolyte is the most important part of an SOFC,
oxide ion conductors applicable in SOFCs became the
hot topic of modern research. The main requirement is
to find a stable dense electrolyte material with
increased conductivity at intermediate temperature. Two commercial electrolytes, yttria stabilized
zirconia (YSZ) and gadolinia doped ceria (GDC), are far to be ideal. The use of YSZ requires operating
temperatures above 1000 °C while devices based on GDC are not efficient enough due to GDC lower
conductivity at intermediate temperatures.
The best candidate for an electrolyte in intermediate temperature SOFCs is undoubtedly fluorite
structured bismuth oxide, i.e. δ-Bi2O3, being the fastest known ionic conductor. However, this material is
unstable upon heating/cooling but the use of dopant, such as Tm, led to the impressive stability and high
conductivity at intermediate temperatures [1]. Our findings indicated that Lu-doped δ-Bi2O3 could show
even better performances since Lu is smaller and more rigid dopant than Tm.
In this study, the possibility to stabilize -Bi2O3 in Bi2O3–Lu2O3 system was investigated. Two
starting mixtures of α-Bi2O3 and Lu2O3 with the following compositions (Bi1–xLux)2O3, x = 0.20 and 0.25,
were dry homogenized in an agate mortar, heat treated at 750 °C for 3 h and then slowly cooled. The
obtain powders were characterized by XRD and DTA techniques. Based on these results, the targeted
cubic single-phase δ-Bi2O3 was successfully obtained within both systems. The unit cell parameter of
obtained Lu-doped -Bi2O3 decreases as the dopant content increases, as expected since Lu3+ is smaller
cation than Bi3+. According to cyclic DTA curves, no phase transitions (25 – 980 °C) were observed for
both phases, (Bi0.8Lu0.2)2O3 and (Bi0.75Lu0.25)2O3, indicating that these -Bi2O3 phases are stable.
Afterwards, half of obtained quantity of each powder was mechanochemically treated (in
planetary ball mill Retsch PM-100) in order to decrease the crystallite size. Namely, before performing
EIS measurements the powders undergo to pressing and then sintering to obtain dense ceramic pellets.
This is also important for their future application in SOFC since the density of almost 100% is mandatory
in order to avoid the direct contact of air (oxygen) and fuel (hydrogen). The density of sintered pellets
obtained from both untreated and mechanochemically treated powders will be compared. Using EIS
technique, the ionic conductivity will be measured for the samples having the highest density. We expect
that these materials will exhibit the conductivities which are higher than those obtained for Tm-doped
-Bi2O3 (0.1 – 0.4 S cm–1 at 550 – 800 °C).
Such stability and extraordinary conductivity would open the possibility for application of
(Bi0.8Lu0.2)2O3 and (Bi0.75Lu0.25)2O3, which could result in the significant enhancement of electrochemical
performance of intermediate temperature SOFCs but also in their good stability over long time service.

AB  - The high temperature phase of bismuth oxide (δ-Bi2O3) is a promising material
for application as an electrolyte for solid oxide fuel cells (SOFCs), due to its high
oxygen ion conductivity. Doping with rare earth cations stabilizes δ-Bi2O3 phase
down to room temperature. According to literature [1], the ionic conductivity of
such δ-Bi2O3 is not significantly decreased even at 600 °C. This opens the
possibility to lower SOFC operating temperature from 1000 °C to intermediate
temperatures. The main drawbacks of this material are the instability in reducing
atmosphere and reactivity toward electrode materials. Bismuth ruthenate (Bi2Ru2O7)
was chosen as a potential electrode material because of its chemical stability,
compatibility with δ-Bi2O3 and metal-like electronic conductivity.
Stoichiometric mixtures of Bi2O3 with Tm2O3 or Lu2O3 were dry homogenized
and heat treated at 750 °C for 3 h in order to obtain δ-Bi2O3 with following
compositions: (Bi0.8Tm0.2)2O3 and (Bi0.75Lu0.25)2O3, respectively. Bi2Ru2O7 was
synthesized similarly, i.e. homogenized mixture of Bi2O3 and RuO2·xH2O was
heated at 900 °C for 3 h. The obtained powders were pressed into disc-shaped
pellets and sintered at 920 °C in case of δ-Bi2O3 and 880 °C in case of Bi2Ru2O7.
Chemical stability of these materials was investigated by exposing the pellets to the
hydrogen and butane atmospheres. Compatibility of electrode and electrolyte
materials was tested by heating a homogenized mixture of Bi2Ru2O7 and
(Bi0.8Tm0.2)2O3 (mass ratio 50:50) at 600 °C. Moreover, a mixture of
(Bi0.75Lu0.25)2O3 and Bi2Ru2O7 (mass ratio 30:70) was pressed into pellet, sintered at
880 °C, and exposed to hydrogen atmosphere in order to evaluate chemical stability
of the mixture under reducing conditions. Both electrolyte- and electrode-supported
configurations were considered with the aim to form a functional fuel cell.

AB  - Determination and monitoring of humidity level is of great importance because
water is one of essential components of the living organisms and materials used by
people. Metal oxides are the most popular materials used as sensing elements for
humidity sensors, due to their excellent thermal and environmental stability, high
mechanical strength, wide range of working temperature, low fabrication cost and
robustness in practical applications. Humidity sensing ability of metal oxide based
ceramic materials can be enhanced by doping with metal cations.
In this work, we present hydrothermal method for preparation of pure and Mgdoped
CuO nanoplatelets and investigate their sensing properties towards humidity.
The proposed method involves autoclaving of copper(II)-acetate solution under
autogenous pressure in alkaline conditions, with different concentrations of Mgdopant
(0, 2.5, 5 and 10 mol%). We have performed thorough structural and optical
investigations of as synthesized material (TEM, XRD, SAED, UV-VIS-NIR).
Furthermore, we have processed obtained powders into functional thick films using doctor blade technique, and their sensing properties were tested in wide range of
temperatures (25, 50, 75 °C) and relative humidities (40–90%), resulting with strong
response and promising response/recovery times.

AB  - The first Co(III) complexes with (1,3-selenazol-2-yl)hydrazones as an unexplored class of ligands were prepared and characterized by NMR spectroscopy and X-ray diffraction analysis. The novel ligands act as NNN tridentate chelators forming octahedral Co(III) complexes. The impact of structural changes on ligands' periphery as well as that of isosteric replacement of sulphur with selenium on the electrochemical and electronic absorption features of complexes are explored. To support the experimental data, density functional theory (DFT) calculations were also conducted. Theoretical NMR chemical shifts, the relative energies and natural bond orbital (NBO) analysis are calculated within the DFT approach, while the singlet excited state energies and HOMO-LUMO energy gap were calculated with time-dependent density functional theory (TD-DFT). The electrophilic f(-) and nucleophilic f(+) Fukui functions are well adapted to find the electrophile and nucleophile centres in the molecules. Both (1,3-selenazol-2-yl)- and (1,3-thiazol-2-yl) hydrazone Co(III) complexes showed potent antimicrobial and antioxidant activity. A significant difference among them was a smaller cytotoxicity of selenium compounds.

AB  - A new Ni(II) complex, [Ni(L)(H2O)] (1), with diethyl 3,3'-(2,2'-(1,1'-(pyridine-2,6-diyl) bis(ethan-1-yl-1-ylidene)) bis(hydrazin-1-yl-2-ylidene)) bis(3-oxopropanoate) ligand (H2L) was synthesized as a potential chemotherapeutic agent. Polidentate ligand was coordinated to Ni(II) NNN-tridentately, in dianionic form, while monodentate water coordination completed square-planar geometry around metal. Structure in the solution was determined by NMR spectroscopy and the same coordination mode was observed in the solid state using IR spectroscopy and further verified by DFT calculations and electrochemical studies. Thermal stability of 1 was determined in both air and nitrogen atmosphere. Anticancer activity of 1 was investigated on acute monocytic leukemia (THP-1) and pancreatic adenocarcinoma (AsPC-1) cell lines. On THP-1 cells 1 induced powerful apoptotic response (ED50 = 10 +/- 3 mu M), which was revealed to be only partially caspase-dependent, with activation of caspase-8 as the dominant course. This suggested that experimentally validated covalent binding of 1 to DNA is not the only mechanism responsible for programmed cell death. This was supported with experiments on AsPC-1 cells. Although treatment of those cells with 1 resulted in poor apoptotic response, cell cycle changes showed concentration-dependent shifts indicating a dual mechanism of activity. This study also reviews the results of preliminary biological screening, which demonstrates that 1 displays a unique pattern of anticancer activity with at least two mechanisms involved.

AB  - A considerable amount of work has been carried out aiming at correlating structures of a large
variety of chlorido-bridged copper(II) complexes and their magnetic properties. Magnetic
properties of such systems depend on the nature of terminal ligands, the coordination geometry
around the copper atoms, and structural distortions from an ideal geometry. Copper(II)
complexes with the condensation derivative of methyl hydrazinoacetate and 2-acetylpyridine
were synthesized and characterized by a single crystal X-ray diffraction. Magnetic properties of
both complexes are discussed based on X-ray structures and SQUID measurements. Magnetostructural
comparisons to structurally similar copper(II) complexes are provided, and a possible
correlation has been established.

AB  - Metal-organic frameworks (MOFs) are regarded as promising materials for applications in
catalysis, separation, gas storage and molecular recognition. Here we report the synthesis and
characterization of novel silver(I) MOF obtained by the reaction of silver(I) nitrate with 1,2,4,5-
benzenetetracarboxylic acid (H4BTEC) and thiomorpholine-4-carbonitrile (tmc). As shown by
X-ray difraction analysis, silver(I) centers have distorted tetrahedral geometry with two
coordination sites occupied by carboxylic oxygen atoms of two H4BTEC, and the other two by
N-atom from nitrile group and S-atom of tmc, respectively. Adjacent silver-carboxylate chains
are connected by two tmc ligands into a 2D polymeric structure. Water molecules between these
2D layers are hydrogen bonded to carboxylic groups from adjacent layers and thus expanding
the 2D structure into a supramolecular 3D structure. Hydrogen bonds make this structure
flexible and suitable for gas absoption. Potential aplication of this coordination polymer as a
hydrogen storage material will be the subject of further investigations.

AB  - Copper(II) complexes with the condensation derivative of methyl hydrazinoacetate and 2-acetylpyridine were synthesized. The X-ray crystal structures for both complexes revealed that they are polymerized isomers. A common feature of both complexes is the bidentate coordination of the ligand by one hydrazone and one pyridine nitrogen atom. In the monomeric complex, the copper(II) center is tetracoordinate, whereas dimerization through chlorido bridges results in a pentacoordinate arrangement about the metal ions in the dimer. The electronic and magnetic properties of both complexes are discussed on the basis of their X-ray structures, electron paramagnetic resonance (EPR) spectroscopy studies, and superconducting quantum interference device (SQUID) magnetization measurements combined with DFT calculations. Magnetostructural comparisons with structurally similar copper(II) complexes are also provided, and a possible correlation has been established. The antitumor activities of the Cu-II complexes were investigated against six different cancer cell lines, and the results suggest that the antiglioma action of the dimeric species is based on oxidative-stress-mediated phosphatidylserine externalization and caspase activation, which indicate apoptosis.

AB  - New Cu(II) and Pd(II) complexes with 2-(2’-pyridyl)-indole ligand HL, modified with
3,4,5-trimetoxybenzoyl group, were synthesized with aim of getting biologically active
transition metal complexes. The complexes were obtained by the reaction of HL with
CuCl2·2H2O or [PdCl2(CH3CN)2], and recrystalized by diffusion of ethanol vapor into
DMSO solution of the crude products. Single crystals of HL and complexes
[Cu2Cl2L2(DMSO)2] and [PdClL(HL)] were obtained and their structures were determined
by X-ray diffraction analysis. Cu(II) complex is a centrosymmetric dimer with squarepyramidal
geometry. One molecule of HL in anionic form is coordinated bidentately via
pyridine and indole nitrogen atoms to Cu(II) ion, forming five-membered chelate ring,
while oxygen atom from carbonyl group is coordinated to another Cu(II) ion. Remaining
two coordination sites are occupied by a chloride ion and a DMSO molecule. Complex
[PdClL(HL)] has square-planar geometry. It contains two molecules of HL. One of them is
coordinated bidentately in monoanionic form via pyridine and indole nitrogen atoms,
forming five-membered chelate ring, while other one is coordinated monodentately in
neutral form via pyridine nitrogen atom. Fourth coordination site is occupied by chloride
ion. Crystal packings of HL and its Pd(II) and Cu(II) complexes are based on hydrogen
bonds and π–π stacking interactions.

vidu monokristala i njihova struktura je određena rendgenskom strukturnom analizom.
Kompleks Cu(II) je centrosimetrični dimer kvadratno-piramidalne geometrije. Jedan
molekul HL je u monoanjonskom obliku bidentatno koordinovan preko indolskog i
piridinskog atoma azota za jedan Cu(II) jon, formirajući petočlani helatni prsten, dok je
kiseonikov atom karbonilne grupe liganda koordinovan za drugi jon Cu(II). Ostala dva
bazalna koordinaciona mesta zauzimaju hloridni jon i molekul DMSO-a. Kompleks

jedan vezan u monoanjonskom obliku bidentatno, preko indolskog i piridinskog atoma

hloridni jon. Kristalno pakovanje HL i njegovih kompleksa je zasnovano na vodoničnim
vezama i π–π steking interakcijama.

abstract = "New Cu(II) and Pd(II) complexes with 2-(2’-pyridyl)-indole ligand HL, modified with
3,4,5-trimetoxybenzoyl group, were synthesized with aim of getting biologically active
transition metal complexes. The complexes were obtained by the reaction of HL with
CuCl2·2H2O or [PdCl2(CH3CN)2], and recrystalized by diffusion of ethanol vapor into
DMSO solution of the crude products. Single crystals of HL and complexes
[Cu2Cl2L2(DMSO)2] and [PdClL(HL)] were obtained and their structures were determined
by X-ray diffraction analysis. Cu(II) complex is a centrosymmetric dimer with squarepyramidal
geometry. One molecule of HL in anionic form is coordinated bidentately via
pyridine and indole nitrogen atoms to Cu(II) ion, forming five-membered chelate ring,
while oxygen atom from carbonyl group is coordinated to another Cu(II) ion. Remaining
