Mg(1) is bonded in a 10-coordinate geometry to one In(3), two equivalent In(1), two equivalent In(2), two equivalent In(4), and three equivalent In(5) atoms. There are five inequivalent In sites. In the first In site, In(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), two equivalent In(3), two equivalent In(5), and three equivalent In(2) atoms. In the second In site, In(2) is bonded in a 2-coordinate geometry to two equivalent Mg(1), two equivalent In(3), and three equivalent In(1) atoms. In the third In site, In(3) is bonded in a 12-coordinate geometry to one Mg(1), two equivalent In(1), two equivalent In(2), two equivalent In(3), two equivalent In(5), and three equivalent In(4) atoms. In the fourth In site, In(4) is bonded in a 2-coordinate geometry to two equivalent Mg(1) and three equivalent In(3) atoms.
