摘要

Two new metal-centered ferrocene complexes Ni(SCN)2(L)4 (1) and Cu(OAc)2(L)2 (2) (L=1-[1-ferrocenylmethyl]imidazole) have been synthesized and characterized by elemental analysis,single crystal X-ray diffraction analysis,spectroscopic and cyclic voltammetric measurements.The geometry of Ni(Ⅱ)in 1 is octahedral,with four ligands in the equatorial plan and two thiocyanate anions at the axial site,while that of Cu(Ⅱ) in 2 is a distorted octahedron formed by two chealted OAc- and two ligands.Single crystal X-ray diffraction studies reveal that there is partial electron delocalization from ferrocene to imidazole in the two complexes.Electrochemical measurements exhibit that complexes 1 and 2 undergo similar reversible one electron redox processes,suggesting that the ferrocene moieties are equivalent and there are no interactions among them.
