CrAlN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Cr(1) is bonded to four equivalent N(1) atoms to form CrN4 tetrahedra that share corners with four equivalent Cr(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 Cr(1)N4 tetrahedra. N(1) is bonded to two equivalent Cr(1) and two equivalent Al(1) atoms to form corner-sharing NAl2Cr2 tetrahedra.
