In the first Cr3+ site, Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six LiO6 octahedra, edges with two equivalent CrO6 octahedra, edges with four VO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 5–6°. There are four shorter (2.03 Å) and two longer (2.05 Å) Cr–O bond lengths. In the second Cr3+ site, Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six LiO6 octahedra, edges with two CrO6 octahedra, edges with four VO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–6°. There are a spread of Cr–O bond distances ranging from 2.03–2.05 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, one V3+, and two Cr3+ atoms to form OLi3VCr2 octahedra that share corners with six OLi3V2Cr octahedra and edges with twelve OLi3VCr2 octahedra. The corner-sharing octahedra tilt angles range from 0–2°. In the second O2- site, O2- is bonded to three Li1+, one V3+, and two equivalent Cr3+ atoms to form OLi3VCr2 octahedra that share corners with six OLi3V2Cr octahedra and edges with twelve OLi3VCr2 octahedra. The corner-sharing octahedra tilt angles range from 0–1°.
