Abstract This paper describe the preparation of new ligand bis-(n-butylthio)ethane (L) from the reaction of dibromoethane and potassium-n-butylthiolate. Mono nuclear complexes were obtained by direct reaction of the above ligand with CoCl2.6H2O,NiCl2.6H2O and CuCl2.4H2O in 1:1 metal to ligand , while the dinuclear complexes were obtained from the reaction with SbCl3 or Bi(NO3)3 in 2:2 metal to ligand. Trinuclear complexes of general formula [M´2M(L)2X6]Cl2 were obtained from the reaction of [M´2(L)2X6], M´= Sb+3 or Bi+3 with metal chloride in 1:1 molar ratio, M=Co+2, Ni+2 or Cu+2. The prepared complexes were characterized by metal analysis, IR,U.V-visible spectroscopy, conductivity and magnetic measurements.
