Title: Materials Data on Li3Ti(CoO3)2 by Materials Project

Abstract

Li3Ti(CoO3)2 is Caswellsilverite-derived structured and crystallizes in the monoclinic C2/m 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 two equivalent CoO6 octahedra, corners with four equivalent TiO6 octahedra, edges with two equivalent TiO6 octahedra, edges with four equivalent CoO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 1–6°. There are two shorter (2.09 Å) and four longer (2.22 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one TiO6 octahedra, corners with five equivalent CoO6 octahedra, edges with two equivalent TiO6 octahedra, edges with four equivalent CoO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 3–10°. There are a spread of Li–O bond distances ranging from 2.13–2.17 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six LiO6 octahedra, edges with two equivalent TiO6 octahedra, edges with four equivalent CoO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tiltmore » angles range from 4–6°. There is two shorter (1.95 Å) and four longer (2.01 Å) Ti–O bond length. Co+2.50+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six LiO6 octahedra, edges with two equivalent TiO6 octahedra, edges with four equivalent CoO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 1–10°. There are a spread of Co–O bond distances ranging from 1.97–2.16 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Li1+, one Ti4+, and two equivalent Co+2.50+ atoms to form a mixture of edge and corner-sharing OLi3TiCo2 octahedra. The corner-sharing octahedra tilt angles range from 0–8°. In the second O2- site, O2- is bonded to three Li1+ and three equivalent Co+2.50+ atoms to form a mixture of edge and corner-sharing OLi3Co3 octahedra. The corner-sharing octahedra tilt angles range from 0–8°. In the third O2- site, O2- is bonded to three Li1+, two equivalent Ti4+, and one Co+2.50+ atom to form a mixture of edge and corner-sharing OLi3Ti2Co octahedra. The corner-sharing octahedra tilt angles range from 0–5°.« less
