该文报道了N,N′-(2-苯并咪唑基甲基)亚氨基甲基膦酸{bbimpH_2,[(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!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!离子之间存在铁磁性相互作用。
This paper reports two nickel compounds, Ni2 (bbimp) 2 (4,4 (N, N’-dibenzimidazolylmethyl) iminomethylphosphonic acid {bbimpH_2, [(C7H5N2) CH2] 2NCH2PO3H2} ’-bipy) (H2O) 2 · 2H2O (1) and [Ni2 (bbimp) 2 (H2O) 2] [Ni (bbimp) (H2O) 2] 2.4H2O (2). Compound 1 is a neutral binuclear structure of 4,4’-bipyridine as a bridging ligand. Compound 2 contains one neutral [Ni2 (bbimp) 2 (H2O) 2] binuclear molecule and two neutral [Ni (bbimp) (H2O) 2] mononuclear molecules. Two Ni ions in the binuclear molecular unit are bridged by two phosphonate oxygen groups. In compound 2, there is a ferromagnetic interaction between the two Ni ions bound by the phosphonate oxygen.
