Complexes of the type [M(L)(ddtc)2], where M = Mn(II), Co(II), Ni(II), Cu(II) and Zn(II), L = 2,2'-bipyridine or 1,10-phenanthroline and ddtc = diethyldithiocarbamate, have been synthesized and characterized by elemental analyses, IR, electronic, EPR, 1H NMR spectral data, magnetic moment and conductivity measurements. The electrical conductivity of the complexes indicated them to be non-electrolyte in nitrobenzene. The spectroscopic evidences suggest that the complexes have an octahedral environment around the metal ion. Plot of log [Delta/Delta-Delta m] against time was linear suggesting first order kinetics of nuceophilic substitution of [Ni(bpy)(ddtc)2] by chloride ion in nitrobenzene. The results show that the rate of substitution is independent of the concentration of the nucleophile and depends only on the first power of the concentration of the complex.
