Abstract: Two new Zn(II) N-(4-X-phenyl)pyridine-2-yl-methanimine complexes, [Zn(NN´-Cl)Cl2](1) and [Zn(NN´-N(CH3)2)Cl2](2), have been synthesized and characterized by elemental analysis, FT-IR and NMR-1H spectra. The crystal structure of complex 1 was determined by X-ray single crystal diffraction. Experiments performed by Benesi-Hilderbrand method indicate that zinc complexes interact with 2,5-pyridinedicarboxyc acid.

ABSTRACT Mononuclear copper(II) complex [CuLCl2] where L = (2-methylsulfanyl-phenyl)-(phenyl-pyridin-2-yl-methylene)amine, a tridentate NNS donor Schiff base ligand has been synthesized and characterized by microanalysis, IR, UV-Visible spectra and magnetic studies. Crystal structure of the complex has been solved by single crystal X-ray diffraction studies and shows the complex has distorted trigonal bipyramidal geometry.

Key words. Copper(II); NNS donor ligand; five coordinate; IR; structure.
