The μ-alkylidyne complex [Mo2Cp2(μ-SMe)3(μ-CCH2Ph)] (1) reacts with HBF4 in acetonitrile to give the unstable bis-nitrile species [Mo2Cp2(μ-SMe)2(μ-CCH2Ph)](NCCH3)2](BF4) (2). Treatment with either borohydride or chloride converts 2 into [Mo2Cp2(μ-SMe)2(μ-CCH2Ph)(μ-κ1:κ1-BH4)] (3) or [Mo2Cp2(μ-SMe)2(μ-CCH2Ph)(μ-Cl)] (4), respectively. Clean evolution of 4 in non-degassed solvent affords the novel μ-thioalkylidene derivative [Mo2(O)(Cl)Cp2(μ-SMe)(μ-MeSCCH2Ph)](5).
