The structure described by LiMn4O8 is beta indium sulfide-derived structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted LiO6 octahedra that share corners with six equivalent Mn(3)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are three inequivalent Mn sites. In the first Mn site, Mn(1) 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 Li(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with two equivalent Mn(3)O6 octahedra. In the second Mn site, Mn(2) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form MnO6 octahedra that share edges with two equivalent Li(1)O6 octahedra, edges with two equivalent Mn(3)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. In the third Mn site, Mn(3) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Li(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Li(1), one Mn(1), one Mn(2), and one Mn(3) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), one Mn(3), and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Mn(2) and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
