The electron precise Mo(3)(μ(3)-S)(μ-S)(3)(dppe)(3)Br(3) incomplete cuboidal complex with six cluster skeletal electrons (CSE) can be converted to the paramagnetic bicapped Mo(3)(μ(3)-S)(2)(μ-S)(3)(dppe)(3) cluster with an unusual seven metal electron population by treatment with (t)BuSNa, which simultaneously serves as a reducing agent and a source of the additional capping sulfur atom.
具有六个簇骨架电子 (CSE) 的电子精确 [Mo(3)(μ(3)-S)(μ-S)(3)(dppe)(3)Br(3)]+(+) 不完全立方络合物可以通过与 (t)BuSNa 反应转化为顺磁双帽 [Mo(3)(μ(3)-S)(2)(μ-S)(3)(dppe)(3)]+ 簇,其中 (t)BuSNa 同时充当还原剂和额外封端硫原子的来源。该反应导致簇中出现了不寻常的七个金属电子。
