CaIn2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Ca(1) is bonded to four equivalent O(1) atoms to form CaO4 tetrahedra that share corners with twelve equivalent In(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 59-60°. In(1) is bonded to six equivalent O(1) atoms to form InO6 octahedra that share corners with six equivalent Ca(1)O4 tetrahedra and edges with six equivalent In(1)O6 octahedra. O(1) is bonded to one Ca(1) and three equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing OCaIn3 trigonal pyramids.
