Abstract

The propynyl ligand of the trimethyl phosphite substituted tungsten complex [(η⁵-C₅H₅)W(CO)₂{P(OMe) ₃}(CH₂C≡CH)] is converted to an allenyl ligand at room temperature and the reaction of [(η⁵-C₅H ₅)W(CO)₃(CH=C=CH₂)] with [H₂Os ₃(CO)₁₀] yields the coupling product [H₂Os ₆(CO)₂₀(C₆H₈)] (4); the structure of (4), established by X-ray crystallography, confirms the presence of a hexa-1,5-diene ligand with two alkene groups bound to two triosmium clusters in a μ,η²-fashion.
