Title: Materials Data on Li4AlCr3O8 by Materials Project

Abstract

Li4Cr3AlO8 is alpha Po-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent CrO6 octahedra, edges with two equivalent AlO6 octahedra, edges with four equivalent CrO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 5–8°. There are four shorter (2.14 Å) and two longer (2.15 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with six equivalent AlO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Li–O bond lengths are 2.21 Å. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent AlO6 octahedra, edges with four equivalent CrO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 5–8°. There are two shorter (2.01 Å) and four longer (2.03 Å) Cr–O bond lengths. Al3+ ismore » bonded to six equivalent O2- atoms to form AlO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Al–O bond lengths are 1.95 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, two equivalent Cr3+, and one Al3+ atom to form a mixture of corner and edge-sharing OLi3AlCr2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to three equivalent Li1+ and three equivalent Cr3+ atoms to form OLi3Cr3 octahedra that share corners with six equivalent OLi3Cr3 octahedra and edges with twelve equivalent OLi3AlCr2 octahedra. The corner-sharing octahedral tilt angles are 0°.« less
