MgIn2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent In(1)O4 tetrahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with four equivalent In(2)O6 octahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form InO4 tetrahedra that share corners with six equivalent Mg(1)O6 octahedra and corners with six equivalent In(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-61°. In the second In site, In(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form InO6 octahedra that share corners with six equivalent In(1)O4 tetrahedra, edges with two equivalent In(2)O6 octahedra, and edges with four equivalent Mg(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Mg(1), one In(1), and one In(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one In(1), and two equivalent In(2) atoms.
