摘　　要：使Zn(OAc)2·2H2O或Cd(OAc)2·2H2O与邻羧基苯甲酰二茂铁钠(o-OOCC6H4COFcNa;Fc=(η5-C5H5)Fe(η5-C5H4))和1,10-邻菲咯啉(phen)在甲醇中反应,合成了含有混合配体的单核配合物[Zn(o-OOCC6H4COFc)2(phen)(H2O)]·CH3OH(1)和双核配合物｛[Cd(η2-o-OOCC6H4COFc)(μ2-o-OOCC6H4COFc)(phen)]·CH3OH2·H2O｝2(2)。晶体结构表明:在1中,单核的结构单元通过分子间氢键形成了一维的长链结构;在2中,o-FcCOC6H4COO-以及phen均双齿螯合中心Cd!离子,随后在o-FcCOC6H4COO-的双齿桥联下,形成一个双核结构。研究了这2个配合物在DMF溶液中的电化学性能。By the reactions of Zn（OAc）2·2H2O或Cd（OAc）2·2H2O with o-ferrocecarbonyl benzoic acid and 1,10- phenantholine in methanol solution, complexes [Zn（o-OOCC6H4COFc）2（phen）（H2O）] ·CH3OH （1） and {[Cd（η2-o-OOCC6H4COFc）（μ2-o-OOCC6COFc）（phen）]·CH3OH2·82O]2（2） were prepared. Their structures were confirmed by elemental analysis, IR data and X-ray diffraction single crystal structure analyses. In complex 1, the mononuclear [Zn（o-OOCC6H4COFc）2（phen）（H2O）] units are connected by weak hydrogen bonds forming one-dimensional chain. In complex 2, the o-FcCOC6H4COO- units as bridging ligands connect two Cd（Ⅱ） ions forming the dinuclear cores. The solution-state differential pulse voltammetries of the two complexes were determined. The results indicate that the half-wave potential of the ferrocenyl moieties is influenced by the Zn（Ⅱ） or Cd（Ⅱ） ions in 1 or 2. CCDC- 645320, 1; 645321, 2.
