Trapped by a proton : In the formation of Os II −N 2 −Os II dimers, an Os V ≡N complex has been invoked as a transient intermediate but not isolated. Herein conditions are reported that allow Os V ≡N species to be trapped either in acidic, aqueous solutions as a neutral osmium( V ) imido complex (Os V =NH, see structure) or in non‐aqueous solvents, with high concentrations of added reductant, by N − ion transfer before coupling can occur.
