Ce is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to six equivalent Ce(1) and six equivalent Ce(2) atoms to form a mixture of corner, face, and edge-sharing CeCe12 cuboctahedra. In the second Ce site, Ce(2) is bonded to six equivalent Ce(1) and six equivalent Ce(2) atoms to form a mixture of corner, face, and edge-sharing CeCe12 cuboctahedra.

In the first Ce site, Ce(1) is bonded to six equivalent Ce(1) and six equivalent Ce(2) atoms to form a mixture of corner, face, and edge-sharing CeCe12 cuboctahedra. All Ce(1)-Ce(1) bond lengths are 3.32 Å. All Ce(1)-Ce(2) bond lengths are 3.32 Å. In the second Ce site, Ce(2) is bonded to six equivalent Ce(1) and six equivalent Ce(2) atoms to form a mixture of corner, face, and edge-sharing CeCe12 cuboctahedra. All Ce(2)-Ce(2) bond lengths are 3.32 Å.
