Preparation and Characterization of Homo and Heterobinuclear Complexes of Co+2, Ni+2, Cu+2, Zn+2, Cd+2 and Hg+2 with Tetramethylthiurammonosulfide

Some new homo and heterobinuclear complexes of Co(II), Cu(II), Ni(II), Zn(II) Cd(II) and Hg(II) with tetramethylthiurammonosulfide have been prepared in 2:2 molar ratio.The prepared complexes were characterized by their metal contents (Co, Ni, Cu, Zn, Cd and Hg), IR, electronic spectra ,conductivity and magnetic measurements. Conductivities data showed that the complexes were non electrolytes assigning the formulaes [M2 (L)2CL4] or [MM´(L)2CL4]. Explanation for the structural elucidation of these complexes on the bases of magnetic and electronic measurements indicated that the complexes had tetragonal geometry with tetrahedral environment.
