Synthesis and characterization of [OsH(PNP)(bipy)]+ (PNP=N(CHCHPtBu2)2) are reported, as the second osmium(III) hydrido complex next to [OsH(en)2(py)]2+. While the osmium(II) precursor, [OsH(PNP)(bipy)], exhibits two reversible oxidations in the cyclic voltammogram, the product from 2‐electron oxidation could not be isolated due to rapid decay. Thermochemical examinations attribute the stability of the osmium(III) hydride to both thermodynamic and kinetic reasons. In contrast, the high estimated acidity of [OsH(PNP)(bipy)]2+ presumably leads to rapid decay. [ABSTRACT FROM AUTHOR]
