摘　　要：Using Bu4N[Fe(Tp*)(CN)3]- (Tp* = hydrotris(3,5-dimethylpyrazol-l-yl)borate) as the building block to react with Cun and N-methylimidazole, we obtained a one-dimensional (1D) beterobimetallic cyano-bridged chain, [Fe(Tp*)(CN)3]2Cu(N- methylimidazole)2.2H20 (1). The crystal structures and magnetic studies demonstrate that complex 1 exhibits slow relaxation of the magnetization due to strong intrachain ferromagnetic coupling and weak interchain interactions.Using Bu4N[Fe(Tp*)(CN)3]- (Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate) as the building block to react with CuII and N-methylimidazole, we obtained a one-dimensional (1D) heterobimetallic cyano-bridged chain, [Fe(Tp*)(CN)3]2Cu(N-methylimidazole)2·2H2O (1). The crystal structures and magnetic studies demonstrate that complex 1 exhibits slow relaxation of the magnetization due to strong intrachain ferromagnetic coupling and weak interchain interactions.
