Synthesis and Characterization of Co(II),Ni(II),Cu(II) and Zn(II) Complexes with Mixed Ligands Thioether and Ethylenediamine Ligands

Abstract

New bimetallic complexes of the types[M2LCl4],[M2L(en)2Cl4], [M2L(en)2(TP)4], where M=Co(II),Ni(II),Cu(II) and Zn(II), TP =p-aminophenylthiolate were prepared by reacting metal chloride with the ligands 1,1,2,2-tetrakis(p-aminophenylthio)ethylene (L), ethylenediamine (en) and in some case with sodium p-aminophenylthiolate. The aryl thioether ligand together with the complexes have been characterized on the basis of microanalysis (N and M), infrared spectra,electronic spectra,magnetic and conductivity measurements.
