Li2Co3SnO8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form LiO4 tetrahedra that share corners with three equivalent Sn(1)O6 octahedra and corners with nine equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-62°. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra and edges with six equivalent Co(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), two equivalent Co(1), and one Sn(1) atom to form distorted OLiCo2Sn trigonal pyramids that share corners with three equivalent O(2)LiCo3 tetrahedra, corners with nine equivalent O(1)LiCo2Sn trigonal pyramids,  an edgeedge with one O(2)LiCo3 tetrahedra, and edges with two equivalent O(1)LiCo2Sn trigonal pyramids. In the second O site, O(2) is bonded to one Li(1) and three equivalent Co(1) atoms to form distorted OLiCo3 tetrahedra that share corners with three equivalent O(2)LiCo3 tetrahedra, corners with nine equivalent O(1)LiCo2Sn trigonal pyramids, and edges with three equivalent O(1)LiCo2Sn trigonal pyramids.
