Ce2O3 is Spinel-derived structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles are 58°. In the second Ce site, Ce(2) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles range from 56-58°. O(1) is bonded to one Ce(1) and three equivalent Ce(2) atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra.

In the first Ce site, Ce(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles are 58°. All Ce(1)-O(1) bond lengths are 2.41 Å. In the second Ce site, Ce(2) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles range from 56-58°. There are a spread of Ce(2)-O(1) bond distances ranging from 2.37-2.47 Å. O(1) is bonded to one Ce(1) and three equivalent Ce(2) atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra.
