The structure described by MgIn2 crystallizes in the monoclinic Cm space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 7-coordinate geometry to two equivalent Mg(2), two equivalent In(2), two equivalent In(4), and three equivalent In(3) atoms. In the second Mg site, Mg(2) is bonded to two equivalent Mg(1), two equivalent Mg(2), one In(3), two equivalent In(1), two equivalent In(2), and three equivalent In(4) atoms to form a mixture of distorted corner and face-sharing MgMg4In8 cuboctahedra. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 11-coordinate geometry to two equivalent Mg(2), two equivalent In(1), two equivalent In(3), two equivalent In(4), and three equivalent In(2) atoms. In the second In site, In(2) is bonded in a 4-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), and three equivalent In(1) atoms. In the third In site, In(3) is bonded in a 4-coordinate geometry to one Mg(2), three equivalent Mg(1), and two equivalent In(1) atoms. In the fourth In site, In(4) is bonded in a 5-coordinate geometry to two equivalent Mg(1), three equivalent Mg(2), and two equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
