Li2Cr3SnO8 is Spinel-derived structured and crystallizes in the monoclinic C2/c 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 three equivalent Cr(2)O6 octahedra, corners with three equivalent Sn(1)O6 octahedra, and corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-62°. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form CrO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Cr(1)O6 octahedra, edges with two equivalent Cr(2)O6 octahedra, and edges with two equivalent Sn(1)O6 octahedra. In the second Cr site, Cr(2) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form CrO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Cr(1)O6 octahedra.

There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Cr(2), and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded to one Li(1), two equivalent Cr(1), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLiCr2Sn trigonal pyramids. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Cr(1), one Cr(2), and one Sn(1) atom. In the fourth O site, O(4) is bonded to one Li(1), one Cr(1), one Cr(2), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OLiCr2Sn trigonal pyramids.
