MgYAl crystallizes in the hexagonal P-62m space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent Al(1) and two equivalent Al(2) atoms. Y(1) is bonded in a 5-coordinate geometry to one Al(2) and four equivalent Al(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Y(1) atoms. In the second Al site, Al(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Y(1) atoms.
