| 摘要: 该文报道了N，N′-(2-苯并咪唑基甲基)亚氨基甲基膦酸{bbimpH2，[(C7H5N2)CH2]2NCH2PO3H2}的2个镍化合物Ni2(bbimp)2(4，4′-bipy)(H2O)2·2H2O (1)和[Ni2(bbimp)2(H2O)2][Ni(bbimp)(H2O)2]2·4H2O (2)。化合物1是4，4′-联吡啶作为桥连配体的中性双核结构。化合物2含有1个中性的[Ni2(bbimp)2(H2O)2]双核分子与2个中性的[Ni(bbimp)(H2O)2]单核分子。双核分子单元中的2个Ni(Ⅱ)离子被2个膦酸氧桥连。在化合物2中，膦酸氧桥连的2个Ni(Ⅱ)离子之间存在铁磁性相互作用。 |

| Abstract: This paper reports two nickel phosphonates Ni2(bbimp)2(4,4′-bipy)(H2O)2·2H2O (1) and [Ni2(bbimp)2(H2O)2][Ni(bbimp)(H2O)2]2·4H2O (2) based on bis(benzimidazol-2-ylmethyl)imino methylenephosphonic acid {bbimpH2, [(C7H5N2)CH2]2NCH2PO3H2}. Compound 1 has a neutral dinuclear structure in which 4,4′-bipy serves as a bridging ligand. While in compound 2, neutral dimers of [Ni2(bbimp)2(H2O)2], where the Ni(Ⅱ) ions are doubly bridged by phosphonate oxygen atoms, are aggregated with the mononuclear species of [Ni(bbimp)(H2O)2]. Ferromagnetic interactions are mediated between the Ni(Ⅱ) ions through the phosphonate oxygen in compound 2. CCDC: 644282, 1; 644283, 2. |
