The propynyl ligand of the trimethylphosphitesubstituted tungsten complex [(η5-C5H5)W(CO)2P(OMe)3}(CH2CCH)] is converted to an allenyl ligand at room temperature and the reaction of [(η5–C5H5)W(CO)3(CHCCH2)] with [H2Os3(CO)10] yields the coupling product [H2Os6(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
