Li2SnCSO7 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(6) atom to form distorted LiO5 trigonal bipyramids that share corners with two equivalent S(1)O4 tetrahedra and edges with two equivalent Li(1)O5 trigonal bipyramids. Sn(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(5), and two equivalent O(4) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. S(1) is bonded to one O(5), one O(6), and two equivalent O(4) atoms to form SO4 tetrahedra that share corners with four equivalent Li(1)O5 trigonal bipyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one C(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Li(1), one Sn(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Li(1), one Sn(1), and one C(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 S(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Sn(1) and one S(1) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to two equivalent Li(1) and one S(1) atom.
