Li2Cr3SnO8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to one O(1) and three equivalent O(2) atoms to form LiO4 tetrahedra that share corners with three equivalent Sn(1)O6 octahedra and corners with nine equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 59-61°. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) 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. Sn(1) is bonded to six equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra and edges with six equivalent Cr(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1) and three equivalent Cr(1) atoms to form distorted OLiCr3 tetrahedra that share corners with three equivalent O(1)LiCr3 tetrahedra, corners with nine equivalent O(2)LiCr2Sn trigonal pyramids, and edges with three equivalent O(2)LiCr2Sn trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), two equivalent Cr(1), and one Sn(1) atom to form distorted OLiCr2Sn trigonal pyramids that share corners with three equivalent O(1)LiCr3 tetrahedra, corners with nine equivalent O(2)LiCr2Sn trigonal pyramids,  an edgeedge with one O(1)LiCr3 tetrahedra, and edges with two equivalent O(2)LiCr2Sn trigonal pyramids.
