The compound described by P2SeO3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four P2SeO3 clusters. There are four inequivalent P sites. In the first P site, P(1) is bonded to one Se(1), one O(2), one O(5), and one O(6) atom to form distorted corner-sharing PSeO3 tetrahedra. In the second P site, P(2) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(4) atom. In the third P site, P(3) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(3), and one O(6) atom. In the fourth P site, P(4) is bonded to one Se(2), one O(3), one O(4), and one O(5) atom to form distorted corner-sharing PSeO3 tetrahedra. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a single-bond geometry to one P(1) atom. In the second Se site, Se(2) is bonded in a single-bond geometry to one P(4) atom. There are six inequivalent O sites. In the first O site, O(3) is bonded in a bent 120 degrees geometry to one P(3) and one P(4) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one P(2) and one P(4) atom. In the third O site, O(5) is bonded in a bent 120 degrees geometry to one P(1) and one P(4) atom. In the fourth O site, O(6) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the fifth O site, O(1) is bonded in a bent 120 degrees geometry to one P(2) and one P(3) atom. In the sixth O site, O(2) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. is represented by the CIF card [CIF]
