The compound described by Lu2Sn2O7 crystallizes in the cubic Fd-3m space group. Lu(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. Sn(1) is bonded to six equivalent O(2) atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Lu(1) atoms to form OLu4 tetrahedra that share corners with four equivalent O(1)Lu4 tetrahedra, corners with twelve equivalent O(2)Lu2Sn2 tetrahedra, and edges with six equivalent O(2)Lu2Sn2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Lu(1) and two equivalent Sn(1) atoms to form OLu2Sn2 tetrahedra that share corners with two equivalent O(1)Lu4 tetrahedra, corners with twelve equivalent O(2)Lu2Sn2 tetrahedra,  an edgeedge with one O(1)Lu4 tetrahedra, and edges with four equivalent O(2)Lu2Sn2 tetrahedra. is represented by the CIF file [CIF]
