Synthesis and characterization of ligating properties of organic disulfides complexes with Co+2, Ni+2 and Cu+2 metal ions


A series of new complexes of the type [M(L)Cl2], [M(L)2Cl2] and [M(L)2]Cl2, where L= L1 or L2 , L1= 2,2`-thiosalyciylic acid disulfide, L2=dibenzyl disulfide, M=Co+2, Ni+2 and Cu+2, were prepared and characterized by molar conductance, IR, UV/Vis spectral studies, magnetic measurements and metal content analysis. Magnetic moment and electronic spectra indicate that the some of the complexes show a tetrahedral geometry and, the others show an octahedral geometry.
