| 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(II)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。 |

| Abstract: By the reactions of Zn(OAc)2·2H2O or 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-OOCC6H4COFc)(phen)]·CH3OH2·H2O}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. |
