The material structure described by Mn4FeO8 is beta indium sulfide-derived structured and crystallizes in the monoclinic C2/m space group. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form distorted MnO6 octahedra that share corners with six equivalent Mn(2)O6 octahedra, edges with two equivalent Fe(1)O6 octahedra, and edges with four equivalent Mn(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-14°. In the second Mn site, Mn(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra, edges with two equivalent Fe(1)O6 octahedra, and edges with four equivalent Mn(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-14°. In the third Mn site, Mn(3) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, edges with two equivalent Mn(3)O6 octahedra, and edges with two equivalent Fe(1)O6 octahedra. Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with four equivalent Mn(3)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Mn(3) and one Fe(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mn(1), one Mn(2), one Mn(3), and one Fe(1) atom. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Mn(1), one Mn(2), and two equivalent Mn(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
