The crystal structure described by Sb2O5 crystallizes in the orthorhombic Cmcm space group. Sb(1) is bonded to one O(1), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 32-44°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Sb(1) atoms. In the second O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sb(1) atoms. In the third O site, O(2) is bonded in a water-like geometry to two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
