Materials Data on LiMn3O4 by Materials Project
LiMn3O4 is Caswellsilverite-like structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent MnO6 octahedra, edges with two equivalent LiO6 octahedra, and edges with ten MnO6 octahedra. The corner-sharing octahedra tilt angles range from 0–5°. There are two shorter (2.15 Å) and four longer (2.28 Å) Li–O bond lengths. There are three inequivalent Mn+2.33+ sites. In the first Mn+2.33+ site, Mn+2.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent MnO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with eight MnO6 octahedra. The corner-sharing octahedra tilt angles range from 1–6°. There are a spread of Mn–O bond distances ranging from 2.13–2.27 Å. In the second Mn+2.33+ site, Mn+2.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent MnO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with eight MnO6 octahedra. The corner-sharing octahedra tilt angles range from 1–6°. There are a spread of Mn–O bond distances ranging from 2.12–2.30 Å. In the third Mn+2.33+ site, Mn+2.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent LiO6 octahedra, and edges with ten MnO6 octahedra. The corner-sharing octahedra tilt angles range from 0–5°. There are a spread of Mn–O bond distances ranging from 2.07–2.29 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+ and four Mn+2.33+ atoms to form a mixture of corner and edge-sharing OLi2Mn4 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to one Li1+ and five Mn+2.33+ atoms to form OLiMn5 octahedra that share corners with six equivalent OLiMn5 octahedra and edges with twelve OLi2Mn4 octahedra. The corner-sharing octahedral tilt angles are 0°.
