In the first Mg site, Mg(1) is bonded in a 5-coordinate geometry to one Ga(2), two equivalent Ga(1), and three equivalent Ga(3) atoms. In the second Mg site, Mg(2) is bonded in a 7-coordinate geometry to two equivalent Ga(2), two equivalent Ga(3), and three equivalent Ga(1) atoms. In the third Mg site, Mg(3) is bonded in a 7-coordinate geometry to two equivalent Ga(1), two equivalent Ga(3), and three equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 7-coordinate geometry to two equivalent Mg(1), two equivalent Mg(3), three equivalent Mg(2), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 12-coordinate geometry to one Mg(1), two equivalent Mg(2), three equivalent Mg(3), two equivalent Ga(1), two equivalent Ga(2), and two equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 7-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), three equivalent Mg(1), and two equivalent Ga(2) atoms.
