The material structure described by Mg5In2 crystallizes in the monoclinic C2/m space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent In(1) and two equivalent In(2) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to two equivalent In(1) and two equivalent In(2) atoms. In the third Mg site, Mg(3) is bonded to two equivalent In(1) and two equivalent In(2) atoms to form distorted edge-sharing MgIn4 cuboctahedra. In the fourth Mg site, Mg(4) is bonded in a 4-coordinate geometry to two equivalent In(1) and two equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted q6 geometry to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(4) atoms. In the second In site, In(2) is bonded in a distorted q6 geometry to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(4) atoms. is represented by the CIF card [CIF]
