Abstract

The higher nuclearity raft-like cluster Os₆(CO)₂₀(μ-SbPh₂)₂, 5-Os, was isolated from the base hydrolysis of Os₃(CO)₁₁(SbPh₂Cl), 1-Os. The ruthenium analogue, viz., Ru₆(CO)₂₀(μ-SbPh₂)₂, 5-Ru, was obtained from the reduction of Ru₃(CO)₁₂, 7-Ru, with the benzophenone ketyl radical followed by treatment with SbPh₂Cl. These clusters undergo facile ligand substitution reactions with two-electron donors to afford the mono- and disubstituted derivatives M₆(CO)_20-n(μ-SbPh₂)₂(L)_n, (M = Ru or Os; n = 1 (8) or 2 (9); L = PMe₃ (a), PPh₃ (b), or ^tBuNC (c)).
