Abstract

The metallostibine Os₂(CO)₈(μ-SbPh), 2, acts as a good two-electron donor ligand, reacting readily with Group 8 metal carbonyls to give heterometallic clusters. Specifically, it undergoes ligand substitution reaction with Fe₂(CO)₉, Os₃(CO)₁₁(CH₃CN), or Os₃(CO)₁₀(CH₃CN)₂ to afford Os₂Fe(CO)₁₂(μ₃-SbPh), 3, Os₅(CO)₁₉(μ₃-SbPh), 4, or Os₇(CO)₂₆(μ₃-SbPh)₂, 5, respectively, in moderate to high yields. An analogous reaction with Ru₃(CO)₁₁(CH₃CN) afforded another spirocyclic cluster Os₃Ru(CO)₁₄(μ-PhCO)(μ₄-Sb), 9. UV irradiation of 4 afforded the spirocyclic clusters Os₅(CO)₁₈(μ,η²-PhCO)(μ₄-Sb), 6, and Os₅(CO)₁₈(μ,η²-C₆H₄)(μ-H)(μ₄-Sb), 7, while the raft-like cluster Os₅(CO)₁₉(μ₃-SbPh), 8, was obtained when a methanolic solution was exposed to natural light; cluster 5 failed to react under similar conditions. All the new clusters have been characterized spectroscopically and crystallographically, and possible pathways for the formation of 6-9 proposed.
