AB  - A biphasic [Mn(dipya)(H2O)4](tpht)/{[Zn(dipya)(tpht)]•H2O}n complex material, I, (dipya = 2,2’-dipyridylamine, tpht2- = dianion of terephthalatic acid) was synthesized by ligand exchange reaction and characterized by XRPD and FTIR spectroscopy. A ZnO/ZnMn2O4 composite, II, has been prepared via thermal decomposition of precursor I in an air atmosphere at 450°C. XRPD, FTIR and FESEM analyses of II revealed the simultaneous presence of spherical nanoparticles of wurtzite ZnO and elongated nanoparticles of spinel ZnMn2O4. The specific surface area of II was determined by the BET method, whereas the volume and average size of the mesopores were calculated in accordance with the BJH method. The measurements of the mean size, polydispersity index and zeta potential showed colloidal instability of II. Two band gap values of 2.4 and 3.3 eV were determined using UV-Vis diffuse reflectance spectroscopy, while the measurements of photoluminescence revealed that II is active in the blue region of the visible spectrum. Testing of composite II as a pigmentary material showed that it can be used for the colouring of a ceramic glaze.

Композит ZnO/ZnMn2O4, II, добијен је термичком разградњом прекурcopa I у атмосфери ваздуха на 450 °C.

вирцитне структуре и издужених наночестица ZnMn2O4 са структуром спинела. Специфична површина II одређена је BET методом, док су запремина и просечна величина мезопора израчунати у складу са BJH методом. Средња величина, индекс полидисперзије и цета потенцијал измерени су фотонском корелационом спектроскопијом и електрофоретским расејањем светлости и показали су нестабилност композита II. Вредности
ширине забрањене зоне 2,4 и 3,3 eV одређене су UV-Vis дифузно-рефлексионом спектроскопијом, док су мерења фотолуминесценције показала да је II активан у плавој области видљивог дела спектра. Испитивање композита II као пигментног материјала показало је да се може користити за бојење керамичке глазуре.

AB  - In recent years, thermal decomposition studies of transition metal complexes with benzenepolycarboxylate ligands have become an area of a great importance due to the possibility of obtaining useful metal oxides with desirable electrical, magnetic and catalytic properties [1]. As a
contrast to conventional methods for the preparation of metal oxides, such as hydrothermal or sol–
gel treatment, thermolysis is faster, more efficient and environmentally friendly. Mn(II)–dipya
(dipya = 2,2’-dipyridylamine) complex with tetraanion of 1,2,4,5-benzenetetracarboxylic
(pyromellitic, H4pyr) acid, [Mn2(dipya)2(pyr)(H2O)2], has been prepared and characterized by
elemental, spectral and microscopy analyses. Direct thermolysis of the complex up to 1200 °C in an air atmosphere yielded spinel Mn3O4 oxide material. The obtained Mn3O4 has been characterized for its structural, spectroscopic, morphological and optical properties. The possibilities of using this oxide as photocatalyst or co-photocatalyst for removing textile organic dyes, as well as inorganic pigmentary material, were also investigated and discussed.
