Preparation and spectral characterization of Schiff base ligand and Cu(II), Co(II), Zn(II), Cd(II) metal complexes

Abstract

Schiff base ligand 2-((3,5-dibromo-2-hydroxybenzylidene) amino)acetic acid derived from 3,5-dibromosalicylaldehyde and glycine has been obtained in water and methanol. Complexes of this Schiff base ligand with Cu(II), Co(II), Zn(II), Cd(II) have been prepared with ligand Metal ratio of 2:1. The structures of the prepared complexes have been elucidated on the basis of elemental analyses, electronic spectra, IR, 1H NMR, mass spectra and TGA.
