In the absence of oxygen the photolysis of [Os(NH3)5(N2)]2+ leads to the reduction of the N2 ligand according to [OsII(NH3)5(N2)]2++ H2O → [OsVI(NH3)4N]3++ N2H4 + OH. The photochemical formation of hydrazine from N2 is discussed with regard to the photochemical conversion and storage of solar energy.
