Metal complexes with dihydrazone of malonic acid dihydrazine

Abstract

This research includes synthesis and characterization of transition metal complexes of Cu (II), Co (II) and Ni (II) with hydrazone Schiff base ligand. Schiff base lagand was synthesized by reaction of malonic ester dihydrazide and 5-bromo salicylaldehyde. The structure of obtained complexes was studied by IR and electron spectroscopy. Keywords: hydrazone Schiff base ligand; copper complex; nickel complex; cobalt complex; IR and UV-Vis spectroscopy.
