description: Li(CoO2)3 is Ilmenite-like structured and crystallizes in the triclinic P1 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 distorted LiO6 octahedra that share corners with nine CoO6 octahedra, edges with three CoO6 octahedra, and a faceface with one CoO6 octahedra. The corner-sharing octahedra tilt angles range from 11–52°. There are a spread of Li–O bond distances ranging from 2.14–2.27 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with nine CoO6 octahedra, edges with three CoO6 octahedra, and a faceface with one CoO6 octahedra. The corner-sharing octahedra tilt angles range from 10–50°. There are a spread of Li–O bond distances ranging from 2.16–2.31 Å. There are six inequivalent Co+3.67+ sites. In the first Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share a cornercorner with one LiO6 octahedra, an edgeedge with one LiO6 octahedra, edges with six CoO6 octahedra, and a faceface with one LiO6 octahedra.

In the fourth Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four LiO6 octahedra, an edgeedge with one LiO6 octahedra, and edges with six CoO6 octahedra. The corner-sharing octahedra tilt angles range from 11–52°. There are a spread of Co–O bond distances ranging from 1.92–2.03 Å. In the fifth Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four LiO6 octahedra, an edgeedge with one LiO6 octahedra, and edges with six CoO6 octahedra. The corner-sharing octahedra tilt angles range from 12–48°. There are a spread of Co–O bond distances ranging from 1.86–1.93 Å. In the sixth Co+3.67+ site, Co+3.67+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four LiO6 octahedra, an edgeedge with one LiO6 octahedra, and edges with six CoO6 octahedra. The corner-sharing octahedra tilt angles range from 10–44°. There are a spread of Co–O bond distances ranging from 1.88–1.91 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Co+3.67+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Co+3.67+ atoms.
