The cluster Os₃(CO)₁₁(NCCH₃) oxidatively adds across the Sb鈥揌 bond in SbPh₂H to afford the clusters Os₃(CO)₁₁(H)(渭-SbPh₂) and Os₃(CO)₁₁(渭-H)(渭-SbPh₂)Os₃(CO)₁₁. Similarly, its reaction with Sb₂Ph₄ afforded Os₃(CO)₁₁(渭-SbPh₂)₂Os₃(CO)₁₁ as the major product. In both cases, the intermediate from the oxidative addition reaction was trapped as a W(CO)₅ adduct.
