The structure described by Mn4NiO8 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 MnO6 octahedra that share corners with six equivalent Mn(2)O6 octahedra, edges with two equivalent Ni(1)O6 octahedra, and edges with four equivalent Mn(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-14°. 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 Ni(1)O6 octahedra, and edges with four equivalent Mn(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-14°. 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 Ni(1)O6 octahedra. Ni(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NiO6 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 trigonal non-coplanar geometry to two equivalent Mn(3) and one Ni(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 Ni(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]
