LiFeSnO4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with six equivalent Fe(1)O6 octahedra and corners with six equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-61°. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Fe(1)O6 octahedra, and edges with four equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 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(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), two equivalent Fe(1), and one Sn(1) atom to form distorted OLiFe2Sn trigonal pyramids that share corners with six equivalent O(1)LiFe2Sn trigonal pyramids, corners with six equivalent O(2)LiFeSn2 trigonal pyramids,  an edgeedge with one O(1)LiFe2Sn trigonal pyramid, and edges with two equivalent O(2)LiFeSn2 trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), one Fe(1), and two equivalent Sn(1) atoms to form distorted OLiFeSn2 trigonal pyramids that share corners with six equivalent O(1)LiFe2Sn trigonal pyramids, corners with six equivalent O(2)LiFeSn2 trigonal pyramids,  an edgeedge with one O(2)LiFeSn2 trigonal pyramid, and edges with two equivalent O(1)LiFe2Sn trigonal pyramids.
