InAlN2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. In(1) is bonded to four equivalent N(1) atoms to form InN4 tetrahedra that share corners with four equivalent In(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 In(1)N4 tetrahedra. N(1) is bonded to two equivalent In(1) and two equivalent Al(1) atoms to form corner-sharing NAl2In2 tetrahedra.
