采用[(Tp)Fe(CN)3]-(Tp=hydrotris(pyrazolyl)borate)与Mn(Ac)2·4H2O反应,合成了氰根桥联的异金属三核配合物[Mn(phen)2][(Tp)Fe(CN)3]2·5H2O(1)(phen=1,10-phenanthroline),并对其结构和磁性进行了研究.晶体结构分析结果表明该化合物晶体属于三斜晶系,P(-1)空间群.在该配合物中,Mn(Ⅱ)与2个phen分子及2个[(Tp)Fe(CN)3]-配位,形成一种弯曲的三核结构.磁性测量结果表明,Mn(Ⅱ)和Fe(Ⅲ)之间通过氰根桥联产生弱的反铁磁相互作用.

Using [(Tp)Fe (CN)3]- (Tp =hydrotris(pyrazolyl)borate) as a building block, one trinuclear complex [Mn(phen)2][(Tp)Fe(CN)3]2 ·5H2O (1) (phen=1,10-phenanthroline) was prepared and its structure and magnetic property were studied. Complex 1 crystallizes in the triclinic space group P(-1), which consists of a neutral Mn ⅡFeⅢ2 unit and five H2O molecules. In compound 1, the Mn Ⅱ ion is coordinated by two [(Tp)Fe(CN)3]- moieties through cyano-bridges in cis positions, resulting in a bended trinuclear structure. The magnetic properties have been investigated in the range of temperature 2～300 K. Antiferromagnetic coupling occurs in cyano-bridged MnⅡ-NC-FeⅢ.CCDC: 611689.
