Materials Data on LiMn4O8 by Materials Project
LiMn4O8 is beta indium sulfide-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with six equivalent MnO6 octahedra and edges with six MnO6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are two shorter (2.08 Å) and four longer (2.25 Å) Li–O bond lengths. There are three inequivalent Mn+3.75+ sites. In the first Mn+3.75+ site, Mn+3.75+ is bonded to six O2- atoms to form MnO6 octahedra that share edges with two equivalent LiO6 octahedra and edges with six MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.92–1.97 Å. In the second Mn+3.75+ site, Mn+3.75+ is bonded to six O2- atoms to form MnO6 octahedra that share edges with two equivalent LiO6 octahedra and edges with six MnO6 octahedra. There is four shorter (1.95 Å) and two longer (1.96 Å) Mn–O bond length. In the third Mn+3.75+ site, Mn+3.75+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent LiO6 octahedra and edges with six MnO6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are four shorter (1.98 Å) and two longer (2.21 Å) Mn–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Mn+3.75+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Mn+3.75+ atoms. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to three Mn+3.75+ atoms.
