Three new compounds based on the cationic complex [Fe(III)(3-R-salEen)(2)]+ (salEen stands for N-(2-ethylamino)ethyl)-salicylaldimine, R = H, CH(3)O) with the electroactive Ni(dmit)(2) species as a counterion (dmit stands for 1,3-dithia-2-thione-4,5-dithiolato) have been synthesized and structurally and magnetically characterized. Compound 1 ([Ni(dmit)(2)][Fe(3-OMe-salEen)(2)]. CH(3)OH) shows an apparent hysteresis loop, due to an irreversible desolvatation process. Compound 2 (Ni(dmit)(2)Fe(salEen)(2)) exhibits a gradual and incomplete spin transition. Compound 3 (Ni(dmit)(2)Fe(salEen)(2), 6CH(3)CN) is a fractional oxidation state complex, which behaves like a semiconductor and exhibits a gradual but complete spin transition between 300 and 4 K.
基于阳离子配合物[Fe(III)(3-R-salEen)(2)]+（salEen代表N-(2-乙氨基)乙基水杨醛亚胺，R = H，CH(3)O），以电活性Ni(dmit)(2)物种（dmit代表1,3-二硫杂-2-硫酮-4,5-二硫醇盐）作为抗衡离子，合成了三种新化合物，并对其进行了结构和磁性表征。化合物1（[Ni(dmit)(2)][Fe(3-OMe-salEen)(2)]. CH(3)OH）由于不可逆的去溶剂化过程而显示出明显的磁滞回线。化合物2（Ni(dmit)(2)Fe(salEen)(2)）表现出逐渐且不完全的自旋转变。化合物3（Ni(dmit)(2)Fe(salEen)(2), 6CH(3)CN）是一种分数氧化态配合物，其行为类似于半导体，在300至4 K之间表现出逐渐但完全的自旋转变。
