The crystal structure described by Fe4Al(CuO4)3 crystallizes in the cubic Im-3 space group. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and faces with two equivalent Al(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 45°. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Al(1) is bonded to twelve equivalent O(1) atoms to form AlO12 cuboctahedra that share faces with eight equivalent Fe(1)O6 octahedra. O(1) is bonded in a distorted trigonal planar geometry to two equivalent Fe(1), one Cu(1), and one Al(1) atom. is represented by the CIF file [CIF]
