The crystal structure described by NaSn4(PO4)3 crystallizes in the trigonal R3c space group. Na(1) is bonded in a 9-coordinate geometry to three equivalent O(2), three equivalent O(3), and three equivalent O(4) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(4) atom. 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 bent 150 degrees geometry to one Sn(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Sn(1), and one P(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Na(1), one Sn(2), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Na(1), one Sn(1), and one P(1) atom. is represented by the CIF card [CIF]
