Аннотация
Zinc halide complexes of thionicotinamide (TNA) having the general formula [Zn(TNA)2X2] (X = Cl-, Br-, I-) are prepared and characterized by thermal analysis, IR and NMR spectroscopy. The crystal structure of one of them, dichloridobis(thionicotinamide-кN)zinc(II), [Zn(TNA)2Cl2] (1), is determined using X-ray crystallography. In 1, the zinc atom is coordinated by two thionicotinamide ligands through nitrogen atoms and two chloride ions in a distorted tetrahedral coordination environment. The molecular structure of the complex is stabilized through intermolecular hydrogen bonding.
