The structure described by P2O5 crystallizes in the orthorhombic Pmmm space group. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form corner-sharing PO6 octahedra. The corner-sharing octahedral tilt angles range from 0-54°. In the second P site, P(2) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing PO6 octahedra. The corner-sharing octahedral tilt angles range from 0-54°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one P(1) and two equivalent P(2) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent P(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent P(2) atoms. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent P(1) atoms. is represented by the CIF file [CIF]
