YAlN2 crystallizes in the tetragonal I-42d space group. Y(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. Al(1) is bonded to four equivalent N(1) atoms to form distorted corner-sharing AlN4 tetrahedra. N(1) is bonded in a 4-coordinate geometry to two equivalent Y(1) and two equivalent Al(1) atoms.
