The compound described by P2O3 is Indium-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two tetraphosphorus hexaoxide molecules. There are three inequivalent P sites. In the first P site, P(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. In the second P site, P(2) is bonded in a distorted trigonal non-coplanar geometry to one O(4) and two equivalent O(3) atoms. In the third P site, P(3) is bonded in a distorted trigonal non-coplanar geometry to one O(4) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one P(2) and one P(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
