A quantum of light for nitrogen : An intramolecular photoredox reaction leads to the reductive cleavage of dinitrogen upon metal‐to‐ligand charge transfer (MLCT) excitation. The primary photochemical step is assumed to proceed by formation of an Os VI nitride complex (see scheme). Secondary reactions modify the product formation.
