Materials Data on Li6Ti2O7 by Materials Project
Abstract
Li6Ti2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form LiO5 trigonal bipyramids that share corners with six LiO5 square pyramids, corners with three equivalent LiO5 trigonal bipyramids, edges with four equivalent 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 five LiO5 square pyramids, corners with four equivalent LiO5 trigonal bipyramids, edges with four equivalent TiO6 octahedra, edges with two equivalent LiO5 square pyramids, and edges with two equivalent LiO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 2.00–2.09 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 four LiO5 square pyramids, corners with two equivalent LiO5 trigonal bipyramids, edges with three equivalent TiO6 octahedra, edges with three LiO5 square pyramids, and edges with two equivalent LiO5 trigonal bipyramids.
