Synthesis and Characterization of Dipeptide Schiff Base Complexes of Copper(Ⅱ), Zinc(Ⅱ), Nickel(Ⅱ) and Cobalt(Ⅱ)

Institute of Chemical Crystallography, Tianjin Normal University, Tianjin 300071

Received Date: 9 January 1997

A new Schiff base (LK) obtained from 2,4,-dihydroxybenzaldehyde and glycyl-DL-phenylalanine reacted with Cu(Ⅱ),Zn(Ⅱ),Ni(Ⅱ) and Co(Ⅱ) to yield new complexes.The complexes were characterized by elemental analyses,molar conductance,¹H NMR,DTA,TG,BR and UV spectroscopy.In these complexes the ligand is coordinated to the metal through its phenolic oxygen,carboxyl oxygen,imino nitrogen and amide nitrogen.All complexes are non-electrolytes and four-coordinated with 1:1 (metal:ligand) stoichiometry.The probable structure of the complexes is suggested.
