The structure described by Ce2UO6 is Fluorite-derived structured and crystallizes in the orthorhombic Immm space group. U(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Ce(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. There are two 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 six equivalent O(2)Ce2U2 tetrahedra, corners with ten equivalent O(1)Ce3U tetrahedra, edges with two equivalent O(2)Ce2U2 tetrahedra, and edges with four equivalent O(1)Ce3U tetrahedra. In the second O site, O(2) is bonded to two equivalent U(1) and two equivalent Ce(1) atoms to form OCe2U2 tetrahedra that share corners with four equivalent O(2)Ce2U2 tetrahedra, corners with twelve equivalent O(1)Ce3U tetrahedra, edges with two equivalent O(2)Ce2U2 tetrahedra, and edges with four equivalent O(1)Ce3U tetrahedra. is represented by the CIF file [CIF]
