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
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., Novi kompleksi Cu(II) i Pd(II) sa 2-(2’-piridil)-indolskim ligandom HL, modifikovanim
dodatkom 3,4,5-trimetoksibenzoil grupe, sintetisani su sa ciljem dobijanja biološki
aktivnih kompleksa prelaznih metala. Kompleksi su sintetisani reakcijom HL sa
CuCl2·2H2O, odnosno [PdCl2(CH3CN)2], a prekristalisani difuzijom etanolnih para u DMSO
rastvor sirovih proizvoda. HL i kompleksi [Cu2Cl2L2(DMSO)2] i [PdClL(HL)] su dobijeni u
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
[PdClL(HL)] je kvadratno-planarne geometrije. Sadrži dva molekula liganda, od kojih je
jedan vezan u monoanjonskom obliku bidentatno, preko indolskog i piridinskog atoma
azota formirajući petočlani helatni prsten. Drugi molekul liganda je vezan monodentatno
u neutralnom obliku preko piridinskog azota, a četvrto koordinaciono mesto zazima
hloridni jon. Kristalno pakovanje HL i njegovih kompleksa je zasnovano na vodoničnim
vezama i π–π steking interakcijama.",
