文摘
Three new compounds based on the cationic complex [FeIII(3-R-salEen)2]+ (salEen stands for N-(2-ethylamino)ethyl)-salicylaldimine, R = H, CH3O) with the electroactive Ni(dmit)2 species as a counterion (dmit stands for1,3-dithia-2-thione-4,5-dithiolato) have been synthesized and structurally and magnetically characterized. Compound1 ([Ni(dmit)2][Fe(3-OMe-salEen)2]. CH3OH) shows an apparent hysteresis loop, due to an irreversible desolvatationprocess. Compound 2 ([Ni(dmit)2](NO3)[Fe(salEen)2]2) exhibits a gradual and incomplete spin transition. Compound3 ([Ni(dmit)2]5[Fe(salEen)2]2, 6CH3CN) is a fractional oxidation state complex, which behaves like a semiconductorand exhibits a gradual but complete spin transition between 300 and 4 K.
