The compound described by Ce2UO6 is Fluorite-derived structured and crystallizes in the trigonal P-3m1 space group. U(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. Ce(1) is bonded in a body-centered cubic geometry to one O(2), three equivalent O(1), and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one U(1) and three equivalent Ce(1) atoms to form OCe3U tetrahedra that share corners with three equivalent O(2)CeU3 tetrahedra, corners with six equivalent O(3)Ce4 tetrahedra, corners with seven equivalent O(1)Ce3U tetrahedra, edges with three equivalent O(3)Ce4 tetrahedra, and edges with three equivalent O(2)CeU3 tetrahedra. In the second O site, O(2) is bonded to three equivalent U(1) and one Ce(1) atom to form OCeU3 tetrahedra that share corners with three equivalent O(1)Ce3U tetrahedra, corners with four equivalent O(3)Ce4 tetrahedra, corners with nine equivalent O(2)CeU3 tetrahedra, edges with three equivalent O(1)Ce3U tetrahedra, and edges with three equivalent O(2)CeU3 tetrahedra. In the third O site, O(3) is bonded to four equivalent Ce(1) atoms to form OCe4 tetrahedra that share corners with four equivalent O(2)CeU3 tetrahedra, corners with six equivalent O(1)Ce3U tetrahedra, corners with six equivalent O(3)Ce4 tetrahedra, edges with three equivalent O(1)Ce3U tetrahedra, and edges with three equivalent O(3)Ce4 tetrahedra. is represented by the CIF file [CIF]
