The crystal structure described by Sn3(PO4)2 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to one O(4) and two equivalent O(7) atoms. In the second Sn site, Sn(2) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. In the third Sn site, Sn(3) is bonded in a distorted T-shaped geometry to one O(5), one O(6), and one O(8) atom. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second P site, P(2) is bonded in a tetrahedral geometry to one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(4) is bonded in a bent 120 degrees geometry to one Sn(1) and one P(1) atom. In the second O site, O(5) is bonded in a bent 120 degrees geometry to one Sn(3) and one P(2) atom. In the third O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Sn(3) and one P(2) atom. In the fourth O site, O(7) is bonded in a 3-coordinate geometry to two equivalent Sn(1) and one P(2) atom. In the fifth O site, O(8) is bonded in a distorted bent 150 degrees geometry to one Sn(3) and one P(2) atom. In the sixth O site, O(1) is bonded in a bent 120 degrees geometry to one Sn(2) and one P(1) atom. In the seventh O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sn(2) and one P(1) atom. In the eighth O site, O(3) is bonded in a 2-coordinate geometry to one Sn(2) and one P(1) atom. is represented by the CIF card [CIF]
