The material described by MgIn2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 10-coordinate geometry to four equivalent In(1) and six equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Mg(1), two equivalent In(2), and six equivalent In(1) atoms to form distorted InMg4In8 cuboctahedra that share corners with six equivalent In(1)Mg4In8 cuboctahedra, corners with twelve equivalent In(2)Mg6In2 cuboctahedra, edges with four equivalent In(1)Mg4In8 cuboctahedra, edges with five equivalent In(2)Mg6In2 cuboctahedra, faces with four equivalent In(2)Mg6In2 cuboctahedra, and faces with eight equivalent In(1)Mg4In8 cuboctahedra. In the second In site, In(2) is bonded to six equivalent Mg(1) and two equivalent In(1) atoms to form distorted InMg6In2 cuboctahedra that share corners with four equivalent In(2)Mg6In2 cuboctahedra, corners with twelve equivalent In(1)Mg4In8 cuboctahedra, edges with five equivalent In(1)Mg4In8 cuboctahedra, edges with six equivalent In(2)Mg6In2 cuboctahedra, faces with four equivalent In(1)Mg4In8 cuboctahedra, and faces with four equivalent In(2)Mg6In2 cuboctahedra. is represented by the CIF file [CIF]
