The corner-sharing octahedra tilt angles range from 2–4°. There are two shorter (1.99 Å) and four longer (2.07 Å) Ti–O bond lengths. There are two inequivalent V2+ sites. In the first V2+ site, V2+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six LiO6 octahedra, edges with two VO6 octahedra, edges with four TiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–8°. There are a spread of V–O bond distances ranging from 2.11–2.13 Å. In the second V2+ site, V2+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six LiO6 octahedra, edges with two equivalent VO6 octahedra, edges with four equivalent TiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are a spread of V–O bond distances ranging from 2.05–2.10 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, one Ti4+, and two V2+ atoms to form a mixture of edge and corner-sharing OLi3TiV2 octahedra. The corner-sharing octahedra tilt angles range from 0–6°. In the second O2- site, O2- is bonded to three Li1+, two Ti4+, and one V2+ atom to form OLi3Ti2V octahedra that share corners with six OLi3Ti2V octahedra and edges with twelve OLi3TiV2 octahedra. The corner-sharing octahedra tilt angles range from 0–3°. In the third O2- site, O2- is bonded to three Li1+, one Ti4+, and two equivalent V2+ atoms to form a mixture of edge and corner-sharing OLi3TiV2 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the fourth O2- site, O2- is bonded to three Li1+, two Ti4+, and one V2+ atom to form OLi3Ti2V octahedra that share corners with six OLi3Ti2V octahedra and edges with twelve OLi3TiV2 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. In the fifth O2- site, O2- is bonded to three Li1+, two equivalent Ti4+, and one V2+ atom to form OLi3Ti2V octahedra that share corners with six OLi3Ti2V octahedra and edges with twelve OLi3TiV2 octahedra.
