Abstract

Pyrolysis of the cluster Os₃(μ-H)₃(CO)₁₀(SnM₂H) produced an as yet unidentified purple cluster, which upon reaction with PEt₂Ph at room temperature, gave essentially a quantitative yield of the cluster Os₃(μ-H)₃(CO)₉(μ₃-Sn) 4, The X-ray structure of 4 (as the toluene solvale) shows that it consists of two Os, triangles linked through a -Sn unit, such that one of the Os, triangle is -bonded to the Sn atom (Os-Sn range 2.689(21-2.707(2) A) and the other is bonded via a single covalent bond (Os-Sn = 2.643(2) A). The phosphine ligand occupies the equatorial site on a second osmium atom of the latter Os, moiety that is syn to the Sn atom; the unique bridging hydride ligand is believed to occupy a site that is cis to both the P and Sn atoms. Crystallographic data for compound 4. space group,.
