LiSnPO4 crystallizes in the orthorhombic Pna2_1 space group. Li(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Sn(1)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. Sn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SnO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra and corners with four equivalent Sn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Sn(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 trigonal non-coplanar geometry to one Li(1), one Sn(1), and one P(1) 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(1) atom.
