The structure described by Li2Mn3SnO8 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 Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-62°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Mn(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 Mn(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 Mn(1) atoms to form distorted OLiMn3 tetrahedra that share corners with three equivalent O(1)LiMn3 tetrahedra, corners with nine equivalent O(2)LiMn2Sn trigonal pyramids, and edges with three equivalent O(2)LiMn2Sn trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), two equivalent Mn(1), and one Sn(1) atom to form distorted OLiMn2Sn trigonal pyramids that share corners with three equivalent O(1)LiMn3 tetrahedra, corners with nine equivalent O(2)LiMn2Sn trigonal pyramids,  an edgeedge with one O(1)LiMn3 tetrahedra, and edges with two equivalent O(2)LiMn2Sn trigonal pyramids. is represented by the CIF card [CIF]
