The material structure described by Sb2O5 crystallizes in the cubic Fd-3m space group. Sb(1) is bonded in a 3-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(2) is bonded to six equivalent Sb(1) atoms to form edge-sharing OSb6 octahedra. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Sb(1) and two equivalent O(3) atoms. In the third O site, O(3) is bonded to six equivalent O(1) atoms to form distorted corner-sharing OO6 octahedra. The corner-sharing octahedral tilt angles are 37°. is represented by the CIF file [CIF]
