Materials Data on Li3Mn3O8 by Materials Project
Li3Mn3O8 is Spinel-like structured and crystallizes in the cubic P4_332 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent LiO6 octahedra and corners with nine equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 54–68°. There is three shorter (1.97 Å) and one longer (1.98 Å) Li–O bond length. In the second Li1+ site, Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with six equivalent MnO6 octahedra. All Li–O bond lengths are 2.13 Å. Mn+4.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent LiO4 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 1.88–1.97 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two Li1+ and two equivalent Mn+4.33+ atoms to form a mixture of distorted edge and corner-sharing OLi2Mn2 trigonal pyramids. In the second O2- site, O2- is bonded to one Li1+ and three equivalent Mn+4.33+ atoms to form a mixture of distorted edge and corner-sharing OLiMn3 trigonal pyramids.
