The compound described by Li2Fe3SnO8 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 Fe(1)O6 octahedra, corners with three equivalent Sn(1)O6 octahedra, and corners with six equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-61°. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Fe(2)O6 octahedra. In the second Fe site, Fe(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form FeO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Fe(1)O6 octahedra, edges with two equivalent Fe(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 Fe(1)O6 octahedra, and edges with four equivalent Fe(2)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Fe(1), and two equivalent Fe(2) atoms to form distorted OLiFe3 trigonal pyramids that share corners with three equivalent O(3)LiFe2Sn trigonal pyramids, corners with three equivalent O(1)LiFe3 trigonal pyramids, corners with six equivalent O(2)LiFe2Sn trigonal pyramids,  an edgeedge with one O(3)LiFe2Sn trigonal pyramid, and edges with two equivalent O(2)LiFe2Sn trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), one Fe(1), one Fe(2), and one Sn(1) atom to form distorted OLiFe2Sn trigonal pyramids that share corners with three equivalent O(3)LiFe2Sn trigonal pyramids, corners with three equivalent O(1)LiFe3 trigonal pyramids, corners with six equivalent O(2)LiFe2Sn trigonal pyramids,  an edgeedge with one O(2)LiFe2Sn trigonal pyramid,  an edgeedge with one O(3)LiFe2Sn trigonal pyramid, and  an edgeedge with one O(1)LiFe3 trigonal pyramid.
