The material structure described by PO3 is Copper structured and crystallizes in the orthorhombic Cmce space group. The structure is zero-dimensional and consists of four tetrametaphosphoric acid molecules. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form corner-sharing PO4 tetrahedra. In the second P site, P(2) is bonded to one O(2), one O(4), and two equivalent O(1) atoms to form corner-sharing PO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one P(2) atom. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to one P(1) and one P(2) atom. In the third O site, O(2) is bonded in a single-bond geometry to one P(2) atom. In the fourth O site, O(3) is bonded in a single-bond geometry to one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
