| Abstract: | Zinc(II) complexes of 4-aminoantipyrine (AAP), [Zn(AAP)2X2] (X = Cl–, I–) and [Zn(AAP)(CN)2] · 2H2O were prepared and characterized by elemental analysis, IR and NMR (1H & 13C) spectroscopy. The crystal structure of [Zn(AAP)2Cl2] (1) was determined by X-ray crystallography. The structural analysis of 1 shows that the complex exists as a monomeric nonionic molecule with zinc atom bound to two AAP ligands and two chloride ions adopting a distorted tetrahedral geometry. In [Zn(AAP)2(CN)2] · 2H2O, the appearance of a band at 2162 cm–1 in IR and resonances around 142 ppm in the 13C NMR spectra indicated the binding of cyanide to zinc(II). |
