1,5-Disubstituted 2,4-dithiobiuret selected for the present studies were, 1,5 di-o-tolyl 2,4-dithiobiuret (DOTDTB),1,5-di-p-phenetyl 2,4-dithiobiuret(DPhDTB),1,5-dimethyl 2,4 dithiobiuret(DMDTB). The ligands were synthesized by the standard method and characterized by TLC, elemental analyses I.R.spectra and melting-points. The complexes of these ligands with the metals Co, Ni & Cu were prepared and characterized by elemental analyses, melting-points,magnetic moments, molar conductance I.R. spectra & Potentiometric studies. Tetrahedral structure have been proposed for these complexes.
