[Ar'SnCo] (1, Ar' = CH-2,6{CH-2,6- Pr}), a rare metal-metal bonded cobalt-tin cluster with low-coordinate tin atoms, was prepared by the reaction of [K(thf)][Co(1,5-cod)] (cod = 1,5-cyclooctadiene) with [Ar'Sn(μ-Cl)]. This reaction illustrates a promising synthetic strategy to access uncommon metal clusters. The structure of 1 features a rhomboidal CoSn core with strong metal-metal bonds between tin and cobalt and a weaker tin-tin interaction. Reaction of 1 with white phosphorus afforded [Ar'SnCoP] (2), the first molecular cluster compound containing phosphorus, cobalt and tin.
[Ar'SnCo]（1，Ar' = CH-2,6{CH-2,6- Pr}）是一种具有低配位锡原子的稀有金属-金属键合钴-锡簇合物，通过[K(thf)][Co(1,5-cod)]（cod = 1,5-环辛二烯）与[Ar'Sn(μ-Cl)]反应制备而成。该反应展示了一种获取不常见金属簇合物的有前景的合成策略。1的结构具有一个菱形的CoSn核心，锡和钴之间存在强金属-金属键，以及较弱的锡-锡相互作用。1与白磷反应生成了[Ar'SnCoP]（2），这是首个包含磷、钴和锡的分子簇合物。
