Li2V3SnO8 is Spinel-derived structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra, corners with three equivalent Sn(1)O6 octahedra, and corners with six equivalent V(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-62°. There are two inequivalent V sites. In the first V site, V(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form VO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent V(2)O6 octahedra. In the second V site, V(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent V(1)O6 octahedra, edges with two equivalent V(2)O6 octahedra, and edges with two equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent V(1)O6 octahedra, and edges with four equivalent V(2)O6 octahedra. There are three 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 V(1), and two equivalent V(2) atoms. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one V(1), one V(2), and one Sn(1) atom. In the third O site, O(3) is bonded to one Li(1), two equivalent V(2), and one Sn(1) atom to form distorted corner-sharing OLiV2Sn trigonal pyramids.
