Yb2Sn2O7 crystallizes in the cubic Fd-3m space group. Yb(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 52°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Yb(1) atoms to form OYb4 tetrahedra that share corners with four equivalent O(1)Yb4 tetrahedra, corners with twelve equivalent O(2)Yb2Sn2 tetrahedra, and edges with six equivalent O(2)Yb2Sn2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Yb(1) and two equivalent Sn(1) atoms to form distorted OYb2Sn2 tetrahedra that share corners with two equivalent O(1)Yb4 tetrahedra, corners with twelve equivalent O(2)Yb2Sn2 tetrahedra,  an edgeedge with one O(1)Yb4 tetrahedra, and edges with four equivalent O(2)Yb2Sn2 tetrahedra.
