The corner-sharing octahedra tilt angles range from 2–3°. All Co–O bond lengths are 1.97 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to three Li1+ and three Fe3+ atoms. In the second O2- site, O2- is bonded to three Li1+, two equivalent Fe3+, and one Co3+ atom to form a mixture of corner and edge-sharing OLi3Fe2Co octahedra. The corner-sharing octahedra tilt angles range from 0–3°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to three Li1+ and three Fe3+ atoms. In the fourth O2- site, O2- is bonded to three Li1+, two equivalent Fe3+, and one Co3+ atom to form a mixture of corner and edge-sharing OLi3Fe2Co octahedra. The corner-sharing octahedra tilt angles range from 0–3°.
