Title: Materials Data on LiMn5O8 by Materials Project

Abstract

LiMn5O8 is Spinel-like structured and crystallizes in the cubic P4_332 space group. The structure is three-dimensional. Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with six equivalent MnO4 tetrahedra and edges with six equivalent MnO6 octahedra. All Li–O bond lengths are 2.15 Å. There are two inequivalent Mn3+ sites. In the first Mn3+ site, Mn3+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with three equivalent LiO6 octahedra and corners with nine equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 56–65°. There are three shorter (2.02 Å) and one longer (2.06 Å) Mn–O bond lengths. In the second Mn3+ site, Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent MnO4 tetrahedra, edges with two equivalent LiO6 octahedra, and edges with four equivalent MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.95–2.04 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+ and three Mn3+ atoms. In the second O2- site, O2- is bonded to four Mn3+ atoms to form distortedmore » corner-sharing OMn4 trigonal pyramids.« less
