The compound described by U4ThO10 is Fluorite-derived structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(3) atoms. In the second U site, U(2) is bonded in a body-centered cubic geometry to four equivalent O(2) and four equivalent O(3) atoms. Th(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent U(1) and two equivalent Th(1) atoms to form OTh2U2 tetrahedra that share corners with six equivalent O(3)U4 tetrahedra, corners with ten equivalent O(1)Th2U2 tetrahedra,  an edgeedge with one O(3)U4 tetrahedra, and edges with five equivalent O(1)Th2U2 tetrahedra. In the second O site, O(2) is bonded to four equivalent U(2) atoms to form a mixture of edge and corner-sharing OU4 tetrahedra. In the third O site, O(3) is bonded to two equivalent U(1) and two equivalent U(2) atoms to form OU4 tetrahedra that share corners with four equivalent O(3)U4 tetrahedra, corners with six equivalent O(1)Th2U2 tetrahedra, corners with six equivalent O(2)U4 tetrahedra,  an edgeedge with one O(1)Th2U2 tetrahedra,  an edgeedge with one O(2)U4 tetrahedra, and edges with four equivalent O(3)U4 tetrahedra. is represented by the CIF file [CIF]
