Materials Data on Li4Zr3O8 by Materials Project

Li4Zr3O8 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one ZrO6 octahedra, corners with four LiO6 octahedra, edges with four LiO6 octahedra, and edges with six ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 5–15°. There are a spread of Li–O bond distances ranging from 2.11–2.36 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent ZrO6 octahedra, corners with four equivalent LiO6 octahedra, edges with four LiO6 octahedra, and edges with six ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 7–15°. There are a spread of Li–O bond distances ranging from 2.16–2.31 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with two equivalent ZrO6 octahedra, corners with four equivalent LiO6 octahedra, edges with four LiO6 octahedra, and edges with six ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 5–14°. There are a spread of Li–O bond distances ranging from 2.14–2.30 Å. There are two inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with two LiO6 octahedra, corners with two equivalent ZrO6 octahedra, edges with three ZrO6 octahedra, and edges with eight LiO6 octahedra.

The corner-sharing octahedra tilt angles range from 9–10°. There are a spread of Zr–O bond distances ranging from 2.05–2.28 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+ and two Zr4+ atoms to form OLi3Zr2 square pyramids that share corners with two equivalent OLi3Zr3 octahedra, corners with seven OLi3Zr2 square pyramids, edges with three equivalent OLi3Zr3 octahedra, and edges with five OLi3Zr2 square pyramids. The corner-sharing octahedra tilt angles range from 1–4°. In the second O2- site, O2- is bonded to three Li1+ and three Zr4+ atoms to form OLi3Zr3 octahedra that share a cornercorner with one OLi3Zr3 octahedra, corners with five OLi3Zr2 square pyramids, edges with two equivalent OLi3Zr3 octahedra, and edges with ten OLi3Zr2 square pyramids. The corner-sharing octahedral tilt angles are 6°. In the third O2- site, O2- is bonded to three Li1+ and two equivalent Zr4+ atoms to form OLi3Zr2 square pyramids that share a cornercorner with one OLi3Zr3 octahedra, corners with eight OLi3Zr2 square pyramids, edges with four equivalent OLi3Zr3 octahedra, and edges with four OLi3Zr2 square pyramids. The corner-sharing octahedral tilt angles are 14°. In the fourth O2- site, O2- is bonded to three Li1+ and two Zr4+ atoms to form OLi3Zr2 square pyramids that share corners with two equivalent OLi3Zr3 octahedra, corners with seven OLi3Zr2 square pyramids, edges with three equivalent OLi3Zr3 octahedra, and edges with five OLi3Zr2 square pyramids. The corner-sharing octahedra tilt angles range from 10–16°.
