The heterometallic compound Os3(CO)10(μ-H)(μ-η 3-C(=CHPh)C≡CW(O)2(C5Me5)) (1), which possesses a bridging hydride and a C≡CC=CHPh ligand, is obtained on addition of the diynyl complex (C5Me5)W(O)2(C≡CC≡CPh) to Os3(μ-H)2(CO)10. 1H NMR spectra show the occurrence of three isomers at equilibrium in solution, of which two isomers have been unambiguously characterized by an X-ray diffraction study. During subsequent tests of reactivity we isolated Os3(CO)10(μ-σ:η 2-C≡CCHCHPh)(μ-H) (2) and (C5Me5)W(μ-O)2Os3(CO) 9(μ-σ:η2-C≡CCHCHPh) (3) through two distinct processes initiated by removal of the (C5Me5)W(O)2 fragment and decarbonylation, respectively.
