The reaction of molecular nitrogen with the layered subnitride Sr 2 N leads to intercalation and formation of single‐phase Sr 2 N[N 2 ] 0.25 (≙Sr 4 N 3 ; see scheme) under mild conditions ( T =650°C, p N 2=9 bar). N 2 is reduced to the diazenide stage [N 2 2− ], while half of the strontium is oxidized to Sr 2+ . The intercalation is reversible.
