GdNiAl crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), two equivalent Al(1), and four equivalent Al(2) atoms. In the second Gd site, Gd(2) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), two equivalent Al(1), and four equivalent Al(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to one Gd(1), two equivalent Gd(2), two equivalent Al(1), and four equivalent Al(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Gd(1), four equivalent Gd(2), one Al(1), and two equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 12-coordinate geometry to two equivalent Gd(1), four equivalent Gd(2), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 12-coordinate geometry to two equivalent Gd(1), four equivalent Gd(2), two equivalent Ni(1), two equivalent Ni(2), one Al(1), and one Al(2) atom.
