Materials Data on Li3Mn2O5 by Materials Project
Abstract
Li3Mn2O5 is Caswellsilverite-like structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with three equivalent LiO6 octahedra, corners with three equivalent MnO6 octahedra, edges with three equivalent MnO6 octahedra, and edges with nine LiO6 octahedra. The corner-sharing octahedra tilt angles range from 7–14°. There are three shorter (1.97 Å) and three longer (2.43 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six MnO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six MnO6 octahedra. The corner-sharing octahedra tilt angles range from 3–5°. There are three shorter (2.16 Å) and three longer (2.21 Å) Li–O bond lengths. In the third Li1+ site, Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with six equivalent MnO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 5°. All Li–O bond lengths are 2.19 Å. In the fourth Li1+more »
