The mu-alkylidyne complex [Mo2Cp2(mu-SMe)(3)(mu-CCH2Ph)] (1) reacts with HBF4 in acetonitrile to give the unstable bis-nitrile species [Mo2Cp2(mu-SMe)(2)(mu-CCH2Ph)](NCCH3)(2)](BF4) (2). Treatment with either borohydride or chloride converts 2 into [Mo2Cp2(mu-SMe)(2)(mu-CCH2Ph)(mu-kappa(1):kappa(1)-BH4)] (3) or [Mo2Cp2(mu-SMe)(2)(mu-CCH2Ph)(mu-Cl)] (4), respectively. Clean evolution of 4 in non-degassed solvent affords the novel mu-thioalkylidene derivative [Mo-2(O)(Cl)Cp-2(mu-SMe)(mu-MeSCCH2Ph)](5).
