MgIn2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 9-coordinate geometry to four equivalent In(2) and five equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to five equivalent Mg(1) and three equivalent In(2) atoms. In the second In site, In(2) is bonded in a 12-coordinate geometry to four equivalent Mg(1), three equivalent In(1), and five equivalent In(2) atoms.
MgIn2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 9-coordinate geometry to four equivalent In(2) and five equivalent In(1) atoms. There are two shorter (3.20 Å) and two longer (3.40 Å) Mg(1)-In(2) bond lengths. There are a spread of Mg(1)-In(1) bond distances ranging from 3.17-3.24 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to five equivalent Mg(1) and three equivalent In(2) atoms. There are two shorter (3.22 Å) and one longer (3.48 Å) In(1)-In(2) bond length. In the second In site, In(2) is bonded in a 12-coordinate geometry to four equivalent Mg(1), three equivalent In(1), and five equivalent In(2) atoms.
