The structure described by LiFeMnO4 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 Mn(1)O6 octahedra and corners with six equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-61°. 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 Mn(1)O6 octahedra, and edges with four equivalent Fe(1)O6 octahedra. 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 Mn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Mn(1), and two equivalent Fe(1) atoms to form distorted OLiMnFe2 trigonal pyramids that share corners with six equivalent O(2)LiMn2Fe trigonal pyramids, corners with six equivalent O(1)LiMnFe2 trigonal pyramids,  an edgeedge with one O(1)LiMnFe2 trigonal pyramid, and edges with two equivalent O(2)LiMn2Fe trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), two equivalent Mn(1), and one Fe(1) atom to form distorted OLiMn2Fe trigonal pyramids that share corners with six equivalent O(2)LiMn2Fe trigonal pyramids, corners with six equivalent O(1)LiMnFe2 trigonal pyramids,  an edgeedge with one O(2)LiMn2Fe trigonal pyramid, and edges with two equivalent O(1)LiMnFe2 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
