Yb2V2O7 crystallizes in the cubic Fd-3m space group. Yb(1) is bonded to two equivalent O(1) and six equivalent O(2) atoms to form distorted YbO8 hexagonal bipyramids that share edges with six equivalent Yb(1)O8 hexagonal bipyramids and edges with six equivalent V(1)O6 octahedra. V(1) is bonded to six equivalent O(2) atoms to form VO6 octahedra that share corners with six equivalent V(1)O6 octahedra and edges with six equivalent Yb(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 41°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Yb(1) atoms to form corner-sharing OYb4 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Yb(1) and two equivalent V(1) atoms.
