Abstract

The monosubstituted clusters RuOs₃(μ-H)₂(CO) ₁₂(EPh₃) (where E = P, As, Sb) exhibit isomers in which the group 15 ligand is on an Os or an Ru vertex. Evidence is presented for hydride fluxionality and EPh₃ ligand migration. These processes have been examined by variable temperature NMR studies, and the kinetic parameters estimated.
