Abstract

Two new cluster complexes, Os ₃(CO) ₁₂(Ph)(μ ₃-SnPh), 8 (35% yield), and Os ₄(CO) ₁₆(μ ₄-Sn), 9 (10% yield), were formed when the complex Os ₃(CO) ₁₁(SnPh ₃)(μ-H), 6, was heated to reflux in toluene solvent under a CO atmosphere. Compound 8 was transformed to 9 in 28% yield when a solution in octane solvent was heated to reflux under a CO atmosphere. Biphenyl was a coproduct in this reaction. Compound 8 contains three osmium atoms with a triply bridging SnPh group. The triosmium cluster has opened and there is only one Os-Os bond between the three osmium atoms. Compound 9 contains two Os ₂(CO) ₈ groups held together by a central quadruply bridging tin atom, giving an overall bow-tie structure for the five metal atoms. Two other new compounds, Os ₂(CO) ₆(μ-SnPh ₂) ₂(SnPh ₃) ₂, 10, and HOs(CO) ₄(SnPh ₃), 11, were formed in 51% and 20% yields, respectively, from the reaction of 6 with HSnPh ₃. Compound 10 contains only two osmium atoms linked by an Os-Os bond and two bridging SnPh ₂ ligands. Each osmium atom also contains one terminal SnPh ₃ ligand. Compound 11 contains only one osmium atom. It has one SnPh ₃ ligartd and a hydrido ligand in cis position in the six-coordinate pseudo-octahedral complex. All four new compounds were characterized by single-crystal X-ray diffraction analysis.
