The previously undescribed complex Cp*Os(dppe)H was synthesized starting from either K2OsX6 salts or H2OsBr6 and characterized together with its precursors Cp*Os(COD)X (X = Cl, Br). Protonation of 1 by HBF4 center dot Et2O was studied in CD2Cl2 at 193 K and was found to lead exclusively to cis-[Cp*Os(dppe)(H)(2)]+BF4-, which irreversibly transforms into trans-[Cp*Os(dppe)(H)(2)]+BF4- above 230 K.
