The crystal structure described by Sn2PO5 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), one O(4), and one O(5) atom. In the second Sn site, Sn(2) is bonded in a distorted pentagonal planar geometry to one O(1), one O(2), one O(3), and two equivalent O(5) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Sn(2) and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sn(1), one Sn(2), and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sn(1), one Sn(2), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Sn(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Sn(1) and two equivalent Sn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
