The crystal structure described by U2Y3O10 is Fluorite-derived structured and crystallizes in the monoclinic C2/m space group. U(1) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a body-centered cubic geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. In the second Y site, Y(2) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one U(1), one Y(2), and two equivalent Y(1) atoms to form OY3U tetrahedra that share corners with four equivalent O(3)Y2U2 tetrahedra, corners with four equivalent O(1)Y3U tetrahedra, corners with eight equivalent O(2)Y2U2 tetrahedra,  an edgeedge with one O(3)Y2U2 tetrahedra, edges with two equivalent O(2)Y2U2 tetrahedra, and edges with three equivalent O(1)Y3U tetrahedra. In the second O site, O(2) is bonded to two equivalent U(1), one Y(1), and one Y(2) atom to form OY2U2 tetrahedra that share corners with four equivalent O(2)Y2U2 tetrahedra, corners with four equivalent O(3)Y2U2 tetrahedra, corners with eight equivalent O(1)Y3U tetrahedra,  an edgeedge with one O(3)Y2U2 tetrahedra, edges with two equivalent O(1)Y3U tetrahedra, and edges with three equivalent O(2)Y2U2 tetrahedra. In the third O site, O(3) is bonded to two equivalent U(1) and two equivalent Y(1) atoms to form OY2U2 tetrahedra that share corners with eight equivalent O(2)Y2U2 tetrahedra, corners with eight equivalent O(1)Y3U tetrahedra, edges with two equivalent O(2)Y2U2 tetrahedra, edges with two equivalent O(3)Y2U2 tetrahedra, and edges with two equivalent O(1)Y3U tetrahedra. is represented by the CIF file [CIF]
