Sc2V2O7 crystallizes in the cubic Fd-3m space group. Sc(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. V(1) is bonded to six equivalent O(1) atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sc(1) and two equivalent V(1) atoms to form distorted OSc2V2 tetrahedra that share corners with two equivalent O(2)Sc4 tetrahedra, corners with twelve equivalent O(1)Sc2V2 tetrahedra,  an edgeedge with one O(2)Sc4 tetrahedra, and edges with four equivalent O(1)Sc2V2 tetrahedra. In the second O site, O(2) is bonded to four equivalent Sc(1) atoms to form OSc4 tetrahedra that share corners with four equivalent O(2)Sc4 tetrahedra, corners with twelve equivalent O(1)Sc2V2 tetrahedra, and edges with six equivalent O(1)Sc2V2 tetrahedra.
Sc2V2O7 crystallizes in the cubic Fd-3m space group. Sc(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Sc(1)-O(2) bond lengths are 2.12 Å. All Sc(1)-O(1) bond lengths are 2.35 Å. V(1) is bonded to six equivalent O(1) atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All V(1)-O(1) bond lengths are 1.94 Å. There are two inequivalent O sites.
