The material described by MgIn2 crystallizes in the trigonal R32 space group. Mg(1) is bonded in a 12-coordinate geometry to three equivalent Mg(1), three equivalent In(2), and six equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(2) is bonded to six equivalent Mg(1) and six equivalent In(1) atoms to form a mixture of edge and corner-sharing InMg6In6 cuboctahedra. In the second In site, In(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) and two equivalent In(2) atoms. is represented by the CIF card [CIF]
