P2O5 crystallizes in the orthorhombic Fdd2 space group. P(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing PO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms.
P2O5 crystallizes in the orthorhombic Fdd2 space group. P(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing PO4 tetrahedra. The P(1)-O(1) bond length is 1.44 Å. The P(1)-O(2) bond length is 1.58 Å. There is one shorter (1.56 Å) and one longer (1.58 Å) P(1)-O(3) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms.
