The material structure described by LiSnPO4 crystallizes in the triclinic P-1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(5), one O(8), and two equivalent O(1) atoms to form LiO4 trigonal pyramids that share  a cornercorner with one P(2)O4 tetrahedra, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one Li(1)O4 trigonal pyramid. In the second Li site, Li(2) is bonded to one O(2), one O(4), one O(6), and one O(7) atom to form LiO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted T-shaped geometry to one O(3), one O(5), and one O(7) atom. In the second Sn site, Sn(2) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(6), one O(8), and two equivalent O(4) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(4), and one O(8) atom to form PO4 tetrahedra that share  a cornercorner with one Li(2)O4 tetrahedra and corners with three equivalent Li(1)O4 trigonal pyramids. In the second P site, P(2) is bonded to one O(2), one O(5), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with three equivalent Li(2)O4 tetrahedra and  a cornercorner with one Li(1)O4 trigonal pyramid. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li(1), one Sn(2), and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Li(2), one Sn(2), and one P(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sn(1), one Sn(2), and one P(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Li(2), two equivalent Sn(2), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one Sn(1), and one P(2) atom. In the sixth O site, O(6) is bonded in a distorted linear geometry to one Li(2), one Sn(2), and one P(2) atom. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one Li(2), one Sn(1), and one P(2) atom. In the eighth O site, O(8) is bonded in a distorted T-shaped geometry to one Li(1), one Sn(2), and one P(1) atom. is represented by the CIF file [CIF]
