MgIn2 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to two equivalent In(3), two equivalent In(4), and four equivalent In(2) atoms. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to two equivalent In(1), two equivalent In(4), and four equivalent In(3) atoms. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to two equivalent Mg(2) atoms. In the second In site, In(2) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms. In the third In site, In(3) is bonded in a 6-coordinate geometry to two equivalent Mg(1) and four equivalent Mg(2) atoms. In the fourth In site, In(4) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(2) atoms.
