The structure described by UCe4O10 is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. U(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(4) atoms. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a body-centered cubic geometry to one O(3), one O(4), three equivalent O(1), and three equivalent O(5) atoms. In the second Ce site, Ce(2) is bonded in a body-centered cubic geometry to one O(5), three equivalent O(3), and four equivalent O(2) atoms. There are five 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(3)Ce4 tetrahedra, corners with three equivalent O(5)Ce4 tetrahedra, corners with three equivalent O(4)CeU3 tetrahedra, corners with seven equivalent O(1)Ce3U tetrahedra, edges with three equivalent O(5)Ce4 tetrahedra, and edges with three equivalent O(4)CeU3 tetrahedra. In the second O site, O(2) is bonded to four equivalent Ce(2) atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra. In the third O site, O(3) is bonded to one Ce(1) and three equivalent Ce(2) atoms to form OCe4 tetrahedra that share  a cornercorner with one O(4)CeU3 tetrahedra, corners with three equivalent O(1)Ce3U tetrahedra, corners with six equivalent O(2)Ce4 tetrahedra, corners with six equivalent O(3)Ce4 tetrahedra, edges with three equivalent O(2)Ce4 tetrahedra, and edges with three equivalent O(5)Ce4 tetrahedra. In the fourth O site, O(4) is bonded to three equivalent U(1) and one Ce(1) atom to form OCeU3 tetrahedra that share  a cornercorner with one O(3)Ce4 tetrahedra, corners with three equivalent O(1)Ce3U tetrahedra, corners with three equivalent O(5)Ce4 tetrahedra, corners with nine equivalent O(4)CeU3 tetrahedra, edges with three equivalent O(1)Ce3U tetrahedra, and edges with three equivalent O(4)CeU3 tetrahedra. In the fifth O site, O(5) is bonded to one Ce(2) and three equivalent Ce(1) atoms to form OCe4 tetrahedra that share corners with three equivalent O(1)Ce3U tetrahedra, corners with three equivalent O(4)CeU3 tetrahedra, corners with four equivalent O(2)Ce4 tetrahedra, corners with six equivalent O(5)Ce4 tetrahedra, edges with three equivalent O(1)Ce3U tetrahedra, and edges with three equivalent O(3)Ce4 tetrahedra. is represented by the CIF card [CIF]
