Abstract

Binuclear oxidative addition of Sb-Cl bonds with the clusters Os ₃(CO)₁₁(NCCH₃), 1, or Os₃(CO) ₁₀(NCCH₃)₂, 2, was found to be an effective synthetic route to organometallic clusters and rings containing μ₂-SbPh₂ or μ₃-SbPh moieties. Thus, the reaction of SbPh₂Cl with 1 afforded the tetranuclear ring Os ₃(CO)₁₁(Cl)(μ-SbPh₂), 3, while its reaction with 2 afforded the pentanuclear ring Os₃(CO)₁₀(Cl) ₂(μ-SbPh₂)₂, 6. In each case, two or three isomeric products were isolated depending on the reaction conditions. The analogous reaction of SbPhCl₂ with 1, on the other hand, afforded the spiked triangular cluster Os₃(CO)₁₁(Cl) ₂(μ₃-SbPh), 7, which also existed as two isomers. Pathways for these reactions have been proposed, and the experimental and computational evidence presented.
