Abstract Two isostructural coordination polymers, [MII(N2H4)2F2·2H2O]n where M = Fe (1·Fe) or Co (2·Co) have been synthesized and characterized. Both compounds exhibit double hydrazine bridged 1D chains where MII centers are six-coordinate with octahedral geometry. Magnetic susceptibility measurements reveal that compound 1·Fe exhibits slow magnetic relaxation characteristic of single-ion magnet (SIM) behavior, which is rarely obtained in FeII coordination polymers.

双肼桥联铁（II）链中场致慢磁弛豫

摘要 合成并表征了两种同构配位聚合物[MII(N2H4)2F2·2H2O]n，其中M = Fe (1·Fe) 或Co (2·Co)。两种化合物都表现出双肼桥接的一维链，其中 MII 中心是八面体几何结构的六坐标。磁化率测量表明，化合物 1·Fe 表现出单离子磁体 (SIM) 行为的缓慢磁弛豫特性，这在 FeII 配位聚合物中很少获得。
