Title: Materials Data on Li4Ti7O16 by Materials Project

Abstract

Li4Ti7O16 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.03 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with four equivalent TiO6 octahedra and edges with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 51–52°. There are a spread of Li–O bond distances ranging from 2.04–2.22 Å. In the third Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.87–2.05 Å. There are five inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four TiO6 octahedra, an edgeedge with one LiO6 octahedra, and edges with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 45–53°. There are a spread of Ti–O bond distances ranging from 1.91–2.09 Å.

In the fourth O2- site, O2- is bonded to two Li1+ and two Ti4+ atoms to form distorted OLi2Ti2 tetrahedra that share corners with two OLi2Ti3 square pyramids, corners with two equivalent OLi2Ti2 tetrahedra, a cornercorner with one OLi2Ti2 trigonal pyramid, and edges with two OLi3Ti2 square pyramids. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti4+ atoms. In the sixth O2- site, O2- is bonded in a rectangular see-saw-like geometry to two Li1+ and two Ti4+ atoms. In the seventh O2- site, O2- is bonded to three Li1+ and two equivalent Ti4+ atoms to form OLi3Ti2 square pyramids that share corners with two equivalent OLi2Ti2 tetrahedra, a cornercorner with one OLi2Ti2 trigonal pyramid, edges with two equivalent OLi2Ti3 square pyramids, and edges with two equivalent OLi2Ti2 tetrahedra. In the eighth O2- site, O2- is bonded to one Li1+ and three Ti4+ atoms to form distorted corner-sharing OLiTi3 tetrahedra. In the ninth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Ti4+ atoms. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti4+ atoms. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti4+ atoms. In the twelfth O2- site, O2- is bonded to two Li1+ and two equivalent Ti4+ atoms to form OLi2Ti2 trigonal pyramids that share a cornercorner with one OLi3Ti2 square pyramid and corners with five OLi2Ti2 tetrahedra.« less
