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.
