Trapped by a proton: In the formation of Os -N -Os dimers, an Os ≡N complex has been invoked as a transient intermediate but not isolated. Herein conditions are reported that allow Os ≡N species to be trapped either in acidic, aqueous solutions as a neutral osmium(V) imido complex (Os =NH, see structure) or in non-aqueous solvents, with high concentrations of added reductant, by N ion transfer before coupling can occur.
