描述了一维链 {[(pzTp)FeIII(CN)3][MnII(phen)2][ClO4]}n(1) 的制备、结构和磁性能。它很容易从含有[NEt4][(pzTp)FeIII(CN)3]·H2O、MnII(ClO4)·6H2O和两当量9,10-菲咯啉的甲醇溶液中获得。磁性数据表明，由于高度扭曲的 FeIII(μ-CN)MnII 单元的存在，低自旋 FeIIILS(S= ½) 和高自旋 MnIIHS(S=5/2) 离子经历了弱氰化物介导的反铁磁交换 [Jiso= −0.92(1) cm−1andgiso= 2.06(2)]。
The preparation, structure, and magnetic properties of a one-dimensional chain, {[(pzTp)FeIII(CN)3][MnII(phen)2][ClO4]}n(1), are described. It is readily obtained from methanolic solutions containing [NEt4][(pzTp)FeIII(CN)3]·H2O, MnII(ClO4)·6H2O, and two equivalents of 9,10-phenanthroline. Magnetic data indicate that the low spin FeIIILS(S= ½) and high spin MnIIHS(S=5/2) ions experience weak cyanide-mediated antiferromagnetic exchange [Jiso= −0.92(1) cm−1andgiso= 2.06(2)] owing to the presence of highly distorted FeIII(μ-CN)MnIIunits.
