The material described by U2LaO6 is Fluorite-derived structured and crystallizes in the orthorhombic Immm 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 four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent U(1) and two equivalent La(1) atoms to form OLa2U2 tetrahedra that share corners with four equivalent O(1)La2U2 tetrahedra, corners with twelve equivalent O(2)LaU3 tetrahedra, edges with two equivalent O(1)La2U2 tetrahedra, and edges with four 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)La2U2 tetrahedra, corners with ten equivalent O(2)LaU3 tetrahedra, edges with two equivalent O(1)La2U2 tetrahedra, and edges with four equivalent O(2)LaU3 tetrahedra. is represented by the CIF file [CIF]
