The material structure described by UCdO4 crystallizes in the trigonal R-3m space group. U(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Cd(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded to one U(1) and three equivalent Cd(1) atoms to form OUCd3 tetrahedra that share corners with six equivalent O(1)U3Cd tetrahedra, corners with ten equivalent O(2)UCd3 tetrahedra, edges with three equivalent O(1)U3Cd tetrahedra, and edges with three equivalent O(2)UCd3 tetrahedra. In the second O site, O(1) is bonded to three equivalent U(1) and one Cd(1) atom to form OU3Cd tetrahedra that share corners with six equivalent O(2)UCd3 tetrahedra, corners with ten equivalent O(1)U3Cd tetrahedra, edges with three equivalent O(1)U3Cd tetrahedra, and edges with three equivalent O(2)UCd3 tetrahedra. is represented by the CIF card [CIF]
