The material structure described by LiSn(PO3)3 crystallizes in the triclinic P-1 space group. Li(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(8) atom to form distorted LiO5 square pyramids that share  a cornercorner with one P(2)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. Sn(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), one O(4), and one O(9) atom. There are three inequivalent P sites.

In the third P site, P(3) is bonded to one O(4), one O(6), one O(7), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent Li(1)O5 square pyramids,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Li(1) and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Li(1), one Sn(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Li(1), one Sn(1), and one P(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Sn(1), and one P(3) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one P(1) and one P(3) atom.
