Reactivity of pymS‒SnPh3 (pymS = pyrimidine-2-thiolate) towards two unsaturated triosmium clusters [Os3(CO)10(μ-H)2] and [Os3(CO)8{µ3-Ph2PCH2P(Ph)C6H4}(μ-H)] are investigated. Reaction of pymS‒SnPh3 with [Os3(CO)10(μ-H)2] affords [Os3(CO)10(µ-pymS)(µ-H)] (1) and [Os3(CO)9(µ3-pymS)(µ-H)] (2), while with [Os3(CO)8{µ3-Ph2PCH2P(Ph)C6H4}(μ-H)] leads to the isolation of only [Os3(CO)8(μ-pymS)(μ-H)(μ-dppm)] (3). In both reactions, the products are formed via incorporation of the thiolate part (pymS) of pymS‒SnPh3 into the parent clusters through Sn‒S bond cleavage. Clusters 1–3 have been characterized by a combination of analytical and spectroscopic data together with single crystal X-ray diffraction analysis. Reactions of pymS‒SnPh3 with two unsaturated triosmium clusters have been investigated which resulted in the isolation and characterization of three triosmium clusters containing a pymS ligand.

[Os3(CO)10(μ-H)2] 和 [Os3(CO)8{μ3-Ph2PCH2P(Ph)C6H4}(μ-H)] 与 pymS‒SnPh3（pymS = pyrimidine-2-thiolate）的反应: 含有pymS配体的三锇簇的合成与结构

pymS-SnPh3 (pymS = pyrimidine-2-thiolate) 对两个不饱和三锇簇 [Os3(CO)10(μ-H)2] 和 [Os3(CO)8{μ3-Ph2PCH2P(Ph)C6H4}(μ -H)] 进行调查。pymS‒SnPh3 与 [Os3(CO)10(μ-H)2] 的反应得到 [Os3(CO)10(μ-pymS)(μ-H)] (1) 和 [Os3(CO)9(​​μ3- pymS)(µ-H)] (2)，而使用 [Os3(CO)8{µ3-Ph2PCH2P(Ph)C6H4}(μ-H)] 导致仅分离 [Os3(CO)8(μ- pymS)(μ-H)(μ-dppm)] (3)。在这两个反应中，产物都是通过 pymS-SnPh3 的硫醇盐部分 (pymS) 通过 Sn-S 键裂解并入母体簇中形成的。簇 1-3 已通过分析和光谱数据以及单晶 X 射线衍射分析的组合进行表征。
