Protonation of (μ-H)3M3(μ3-CR)(CO)9 (M = Ru, R = Et or M = Os, R = Me) by dissolution in HSO3CF3 yields H3M3(HCR)(CO)9+, containing a MHC bridge. The products were characterized by 1H and 13C NMR spectroscopy. Decompositions of other protonated methylidyne clusters from CH3R and a variety of metal-containing products.
