Li2BSnO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one O(2), one O(4), and two equivalent O(1) atoms. In the second Li site, Li(2) 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 trigonal pyramids. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. Sn(1) is bonded to one O(2), one O(3), and two equivalent O(4) atoms to form distorted SnO4 trigonal pyramids that share corners with four equivalent Li(2)O4 tetrahedra and corners with two equivalent Sn(1)O4 trigonal pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Li(2), two equivalent Li(1), and one B(1) atom to form corner-sharing OLi3B tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), one B(1), and one Sn(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(2), one B(1), and one Sn(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), and two equivalent Sn(1) atoms.
