In2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent In sites. In the first In site, In(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 54-55°. In the second In site, In(2) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing InO6 octahedra. The corner-sharing octahedral tilt angles are 54°. O(1) is bonded to one In(2) and three equivalent In(1) atoms to form a mixture of corner and edge-sharing OIn4 trigonal pyramids.

In the first In site, In(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 54-55°. There are a spread of In(1)-O(1) bond distances ranging from 2.14-2.23 Å. In the second In site, In(2) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing InO6 octahedra. The corner-sharing octahedral tilt angles are 54°. All In(2)-O(1) bond lengths are 2.19 Å. O(1) is bonded to one In(2) and three equivalent In(1) atoms to form a mixture of corner and edge-sharing OIn4 trigonal pyramids.
