摘要：

Nickel(II) complexes of the general composition Ni(L) X-2 ( where X = Cl, SCN and 1/2 SO4) L= 2,3- dipenyl- 1,4- diaza-7,10-dithia-5,6 : 11,12-dibenzo[ e,k] cyclododeca-1,3-diene[N2S2] ane, (L-1) and L = 1,10-diaza-4,7,13- trithia- 2,3 : 8,9- dibenzo-[b, h]-cyclo-penta-deca-11,15- dione[N2S3] ane (L-2) have been synthesized and characterized by elemental analyses, magnetic moments, IR and electronic spectral studies. The nickel( II) complexes show magnetic moments corresponding to two unpaired electrons except [ Ni( L-1)](NO3)(2), which is diamagnetic. Various ligand field parameters have been calculated and discussed. The electrochemical properties for Ni( II)/Ni(I) couples have been studied extensively.
