Materials Data on Li6Ti2O7 by Materials Project
Abstract
Li6Ti2O7 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 square pyramids that share corners with five LiO5 square pyramids, corners with four equivalent LiO5 trigonal bipyramids, edges with four TiO6 octahedra, and edges with four LiO5 square pyramids. There are a spread of Li–O bond distances ranging from 1.98–2.12 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 square pyramids that share corners with seven LiO5 square pyramids, corners with two equivalent LiO5 trigonal bipyramids, edges with four TiO6 octahedra, edges with three LiO5 square pyramids, and an edgeedge with one LiO5 trigonal bipyramid. There are a spread of Li–O bond distances ranging from 2.00–2.08 Å. In the third Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with three equivalent TiO6 octahedra, corners with five LiO5 square pyramids, a cornercorner with one LiO5 trigonal bipyramid, edges with three TiO6 octahedra, edges with four LiO5 square pyramids, and an edgeedge with one LiO5 trigonal bipyramid.
