The material structure described by ULaO4 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(2) atoms. La(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 La(1) atoms to form OLa3U tetrahedra that share corners with six equivalent O(2)LaU3 tetrahedra, corners with ten equivalent O(1)La3U tetrahedra, edges with three equivalent O(1)La3U tetrahedra, and edges with three equivalent O(2)LaU3 tetrahedra. In the second O site, O(2) is bonded to three equivalent U(1) and one La(1) atom to form OLaU3 tetrahedra that share corners with six equivalent O(1)La3U tetrahedra, corners with ten equivalent O(2)LaU3 tetrahedra, edges with three equivalent O(1)La3U tetrahedra, and edges with three equivalent O(2)LaU3 tetrahedra. is represented by the CIF file [CIF]
