Treatment of the osmium(II) hydrides Cp*Os(P-P)H (Cp* = pentamethylcyclopentadienyl) with methyl trifluoromethanesulfonate (MeOTf) affords osmium(II) triflate complexes with the general formula Cp*Os(P-P)(OTf), where P-P = bis(dimethylphosphino)methane (dmpm), bis(diphenylphosphino)methane (dppm), or 1,2-bis(dimethylphosphino)ethane (dmpe). The aqua complexes [Cp*Os(dmpm)(OH2)][OTf] and [Cp*Os(dppm)(OH2)][OTf] are synthesized by the addition of water to the corresponding anhydrous triflates. The complexes Cp*Os(dppm)(OTf) and [Cp*Os(dmpm)(OH2)][OTf] have been examined crystallographically, and all compounds have been characterized by NMR spectroscopy.
