FeAlN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Fe(1) is bonded to four equivalent N(1) atoms to form FeN4 tetrahedra that share corners with four equivalent Fe(1)N4 tetrahedra and corners with eight equivalent Al(1)N4 tetrahedra. Al(1) is bonded to four equivalent N(1) atoms to form AlN4 tetrahedra that share corners with four equivalent Al(1)N4 tetrahedra and corners with eight equivalent Fe(1)N4 tetrahedra. N(1) is bonded to two equivalent Fe(1) and two equivalent Al(1) atoms to form corner-sharing NAl2Fe2 tetrahedra.
