The crystal structure described by U2YO6 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. Y(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 Y(1) atoms to form OY2U2 tetrahedra that share corners with four equivalent O(1)Y2U2 tetrahedra, corners with twelve equivalent O(2)YU3 tetrahedra, edges with two equivalent O(1)Y2U2 tetrahedra, and edges with four equivalent O(2)YU3 tetrahedra. In the second O site, O(2) is bonded to three equivalent U(1) and one Y(1) atom to form OYU3 tetrahedra that share corners with six equivalent O(1)Y2U2 tetrahedra, corners with ten equivalent O(2)YU3 tetrahedra, edges with two equivalent O(1)Y2U2 tetrahedra, and edges with four equivalent O(2)YU3 tetrahedra. is represented by the CIF file [CIF]
