Complexes of the type [Mpy2(dedtc)2], and [Mpy 2(dpdtc)2], where M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), py = pyridine, dedtc = diethyldithiocarbamate and dpdtc = diphenyldithiocarbamate, have been synthesized and characterized by elemental analyses, magnetic susceptibility, TGA/DSC and IR in the solid-state, and electronic spectroscopy and conductivity measurement studies in solution. The dithiocarbamato moiety has been found to be symmetrically bonded to the metal. The complexes are proposed to have a distorted-octahedral structure. The ligand field parameters 10 Dq, B and β have also been evaluated. The value of β indicates a considerable orbital overlap in the complexes. A two-stage decomposition pattern leading to the formation of respective metal sulfide as the end-product has been observed in all the complexes. Their molar conductance indicated them to be non-electrolyte in nitrobenzene. Copyright
