The compound described by MnFe2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Fe(2)O6 octahedra. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form FeO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra and corners with six equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-62°. In the second Fe site, Fe(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra, edges with two equivalent Fe(2)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 two equivalent Mn(1), one Fe(1), and one Fe(2) atom to form distorted OMn2Fe2 trigonal pyramids that share corners with six equivalent O(1)Mn2Fe2 trigonal pyramids, corners with six equivalent O(2)MnFe3 trigonal pyramids,  an edgeedge with one O(1)Mn2Fe2 trigonal pyramid, and edges with two equivalent O(2)MnFe3 trigonal pyramids. In the second O site, O(2) is bonded to one Mn(1), one Fe(1), and two equivalent Fe(2) atoms to form distorted OMnFe3 trigonal pyramids that share corners with six equivalent O(1)Mn2Fe2 trigonal pyramids, corners with six equivalent O(2)MnFe3 trigonal pyramids,  an edgeedge with one O(2)MnFe3 trigonal pyramid, and edges with two equivalent O(1)Mn2Fe2 trigonal pyramids. is represented by the CIF card [CIF]
