One-Dimensional Mn(III) Coordination Polymer Exhibiting Ferromagnetic Coupling

Mn(III) complexes of 1-(2-hydroxybenzamido)-2-((2-hydroxy-3-methoxybenzylidene)amino)ethane (H3L), mononuclear [Mn(L)(MeOH)(H2O)] (1) and amido-bridged one-dimensional [Mn(L)(H2O)]∞ (2), have been synthesized by the reaction of MnAc3·2H2O with H3L. Magnetic studies revealed that complex 2 exhibits intermetallic ferromagnetic coupling, which is the first one-dimensional high-spin Mn(III) complex with ferromagnetic behavior.

由1-(2-羟基苯甲酰胺)-2-((2-羟基-3-甲氧基苯基)亚甲基)氨基乙烷（H3L）与MnAc3·2H2O反应合成的Mn(III)配合物，包括单核[Mn(L)(MeOH)(H2O)]（1）和酰胺桥连的一维[Mn(L)(H2O)]∞（2）。磁性研究表明，配合物2表现出金属间铁磁性耦合，这是首个具有铁磁行为的单核高自旋Mn(III)配合物。
