Abstract

Four transition metal(II) complexes of each carbohydrazone-bis(2-hydroxynaphthaldehyde) (1) and pyridine-2-carboxaldehyde isonicotinichydrazone (2) ligands have been synthesized and characterized by CHN analyses, FTIR and UV-Visible spectral studies. All transition metal(II) complexes of carbohydrazone/hydrazone ligands have been analyzed by determining their molar conductivity. Two carbohydrazone/hydrazone ligands and their respective Co(II) complexes have also been characterized by 1H NMR spectral study. All transition metal(II) complexes exhibited non electrolytic properties in nature. Spectral studies indicated both of the carbohydrazone/hydrazone ligands (1-2) acted as dinegative tridentate fashion towards the transition metal(II) ions. The proposed structures of the transition metal(II) complexes have been deduced on the basis of elemental analyses and spectral studies. Therefore, a four coordinated molecular structure has been proposed for the synthesized transition metal(II) complexes.
