Synthesis and characterization of copper(II), nickel(II), cobalt(II), zinc(II), cadmium(II) and oxovanadium(IV) complexes of 2-(3-coumarinyl)imidazo[1,2-a]pyridine

Abstract

The complexes of copper(II), nickel(II), cobalt(III), zinc(II), cadmium(II) and oxovanadium(IV) with a newly synthesised ligand 2-(3-coumarinyl)imidazo[1,2-a]pyridine (CIP) have been prepared and characterized on the basis of elemental analysis, magnetic, conductance, spectral (IR, electronic, ESR, PMR), thermal and X-ray powder diffraction studies. In all the complexes, the ligand acts as a neutral bidentate coordinating through > C = 0 (lactone) and > C= N of imidazo group.
