MnFe4CuO8 is Spinel-derived structured and crystallizes in the cubic F-43m space group. Mn(1) is bonded to four equivalent O(1) atoms to form MnO4 tetrahedra that share corners with twelve equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Fe(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form FeO6 octahedra that share corners with three equivalent Mn(1)O4 tetrahedra, corners with three equivalent Cu(1)O4 tetrahedra, and edges with six equivalent Fe(1)O6 octahedra. Cu(1) is bonded to four equivalent O(2) atoms to form CuO4 tetrahedra that share corners with twelve equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Mn(1) and three equivalent Fe(1) atoms to form distorted OMnFe3 trigonal pyramids that share corners with three equivalent O(1)MnFe3 trigonal pyramids, corners with nine equivalent O(2)Fe3Cu trigonal pyramids, and edges with three equivalent O(1)MnFe3 trigonal pyramids. In the second O site, O(2) is bonded to three equivalent Fe(1) and one Cu(1) atom to form distorted OFe3Cu trigonal pyramids that share corners with three equivalent O(2)Fe3Cu trigonal pyramids, corners with nine equivalent O(1)MnFe3 trigonal pyramids, and edges with three equivalent O(2)Fe3Cu trigonal pyramids.
