  Synthesis and Characterization of the W−Os Heterometallic Complex Os₃(CO)₁₀(μ-H)(μ-η³-C(CHPh)C⋮CW(O)₂(C₅Me₅)):  Evidence of Hydride Dislocation on a Triosmium Framework by Crystal Polymorphism

  摘要：

  The heterometallic compound Os-3(CO)(10)(mu-H)(mu-eta(3)-C(=CHPh)C equivalent to CW(O)(2)(C5Me5)) (1), which possesses a bridging hydride and a C equivalent to CC=CHPh ligand, is obtained on addition of the diynyl complex (C5Me5)W(O)(2)(C equivalent to CC=CPh) to Os-3(mu-H)(2)(CO)(10). H-1 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 Os-3(CO)(10)(mu-sigma:eta(2)-C equivalent to CCHCHPh)(mu-H) (2) and (C5Me5)W(mu-O)(2)Os-3(CO)(9)(mu-sigma:eta(2)-C equivalent to CCHCHPh) (3) through two distinct processes initiated by removal of the (C5Me5)W(O)(2) fragment and decarbonylation, respectively.
