The crystal structure described by Th4LaO10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. Th(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. La(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Th(1) and one La(1) atom to form OLaTh3 tetrahedra that share corners with four equivalent O(2)Th4 tetrahedra, corners with twelve equivalent O(1)LaTh3 tetrahedra,  an edgeedge with one O(2)Th4 tetrahedra, and edges with five equivalent O(1)LaTh3 tetrahedra. In the second O site, O(2) is bonded to four equivalent Th(1) atoms to form OTh4 tetrahedra that share corners with sixteen equivalent O(1)LaTh3 tetrahedra, edges with two equivalent O(2)Th4 tetrahedra, and edges with four equivalent O(1)LaTh3 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
