The structure described by Sn4(PO4)3 crystallizes in the hexagonal P6_3 space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(4) atoms. In the second Sn site, Sn(2) is bonded in a distorted T-shaped geometry to three equivalent O(3) 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 four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Sn(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Sn(2) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Sn(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
