Title: Materials Data on LiMn4O8 by Materials Project

Abstract

LiMn4O8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with six MnO6 octahedra, edges with three MnO6 octahedra, and a faceface with one MnO6 octahedra. The corner-sharing octahedra tilt angles range from 14–54°. There are a spread of Li–O bond distances ranging from 2.09–2.29 Å. There are four 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 corners with four MnO6 octahedra, edges with four MnO6 octahedra, and edges with two equivalent LiO5 square pyramids. The corner-sharing octahedra tilt angles range from 49–54°. There are a spread of Mn–O bond distances ranging from 1.91–1.96 Å. In the second Mn+3.75+ site, Mn+3.75+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four MnO6 octahedra, corners with two equivalent LiO5 square pyramids, edges with four MnO6 octahedra, and an edgeedge with one LiO5 square pyramid. The corner-sharing octahedra tilt angles range from 48–54°. There are a spread of Mn–O bond distances ranging from 1.92–2.07 Å. In the third Mn+3.75+ site, Mn+3.75+ is bonded to six O2-more » atoms to form MnO6 octahedra that share corners with four MnO6 octahedra, corners with three equivalent LiO5 square pyramids, and edges with four MnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–52°. There are a spread of Mn–O bond distances ranging from 1.90–2.02 Å. In the fourth Mn+3.75+ site, Mn+3.75+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four MnO6 octahedra, a cornercorner with one LiO5 square pyramid, edges with four MnO6 octahedra, and a faceface with one LiO5 square pyramid. The corner-sharing octahedra tilt angles range from 48–54°. There are a spread of Mn–O bond distances ranging from 1.92–1.99 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted see-saw-like geometry to one Li1+ and three Mn+3.75+ atoms. In the second O2- site, O2- is bonded in a see-saw-like geometry to one Li1+ and three Mn+3.75+ atoms. In the third O2- site, O2- is bonded to one Li1+ and three Mn+3.75+ atoms to form a mixture of distorted edge and corner-sharing OLiMn3 trigonal pyramids. In the fourth O2- site, O2- is bonded to one Li1+ and three Mn+3.75+ atoms to form a mixture of distorted edge and corner-sharing OLiMn3 trigonal pyramids. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Mn+3.75+ atoms. In the sixth O2- site, O2- is bonded to one Li1+ and three Mn+3.75+ atoms to form a mixture of edge and corner-sharing OLiMn3 trigonal pyramids. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to three Mn+3.75+ atoms. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to three Mn+3.75+ atoms.« less
