BaHoFe4O7 crystallizes in the cubic F-43m space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, edges with twelve equivalent Fe(1)O4 tetrahedra, and faces with four equivalent Ho(1)O6 octahedra. Ho(1) is bonded to six equivalent O(1) atoms to form HoO6 octahedra that share corners with twelve equivalent Fe(1)O4 tetrahedra and faces with four equivalent Ba(1)O12 cuboctahedra. Fe(1) is bonded to one O(2) and three equivalent O(1) atoms to form FeO4 tetrahedra that share corners with three equivalent Ho(1)O6 octahedra, corners with six equivalent Fe(1)O4 tetrahedra, and edges with three equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ba(1), one Ho(1), and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a tetrahedral geometry to four equivalent Fe(1) atoms.
