Abstract

Average magnetic moments, μ¯m¯, versus temperature in the range 300−1.8K, and the variation of μ¯m¯ with applied magnetic field, from 0.125 to 2.0T, are reported for [NEt4]3[Fe6M2S8(SPh)6(OMe)3] (M Mo or W). These data have been interpreted in terms of antiferromagnetic spin coupling between the iron atoms within the separate {Fe3MS4} cubane-like clusters of the anions.

类古巴烷簇二聚体[NEt4]3[Fe6M2S8(SPh)6(OMe)3] (M、Mo或W)的自旋交换作用
报道了[NEt4]3[Fe6M2S8(SPh)6(OMe)3] (m Mo或W)的平均磁矩μ¯m¯随温度在300 ~ 1.8K范围内的变化,以及μ¯m¯随外加磁场的变化,从0.125 t到2.0T。这些数据已被解释为在独立的{Fe3MS4}类立方体阴离子簇内的铁原子之间的反铁磁自旋耦合。
