The material described by Sn(PO3)3 crystallizes in the orthorhombic P2_12_12_1 space group. Sn(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(4), one O(5), one O(6), and one O(7) atom. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(5), one O(8), and one O(9) atom to form corner-sharing PO4 tetrahedra. In the second P site, P(2) is bonded to one O(3), one O(6), one O(7), and one O(8) atom to form corner-sharing PO4 tetrahedra. In the third P site, P(3) is bonded to one O(1), one O(3), one O(4), and one O(9) atom to form corner-sharing PO4 tetrahedra. There are nine inequivalent O sites. In the first O site, O(8) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(9) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one P(3) atom. In the fourth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one P(1) atom. In the fifth O site, O(3) is bonded in a bent 120 degrees geometry to one P(2) and one P(3) atom. In the sixth O site, O(4) is bonded in a 2-coordinate geometry to one Sn(1) and one P(3) atom. In the seventh O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one P(1) atom. In the eighth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one P(2) atom. In the ninth O site, O(7) is bonded in a single-bond geometry to one Sn(1) and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
