Title: Materials Data on Li2Ti3O7 by Materials Project

Abstract

Li2Ti3O7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with three equivalent TiO6 octahedra, a cornercorner with one LiO5 trigonal bipyramid, corners with two equivalent LiO4 trigonal pyramids, an edgeedge with one TiO6 octahedra, and edges with two equivalent LiO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 18–81°. There are two shorter (1.99 Å) and two longer (2.18 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with three TiO6 octahedra, corners with two equivalent LiO5 trigonal bipyramids, a cornercorner with one LiO4 trigonal pyramid, an edgeedge with one TiO6 octahedra, edges with two equivalent LiO5 trigonal bipyramids, and edges with two equivalent LiO4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 10–69°. There are a spread of Li–O bond distances ranging from 2.01–2.46 Å. There are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share cornersmore » with two equivalent TiO6 octahedra, a cornercorner with one LiO5 trigonal bipyramid, corners with three equivalent LiO4 trigonal pyramids, and edges with three TiO6 octahedra. The corner-sharing octahedral tilt angles are 31°. There are a spread of Ti–O bond distances ranging from 1.79–2.20 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent LiO5 trigonal bipyramids, an edgeedge with one TiO6 octahedra, an edgeedge with one LiO5 trigonal bipyramid, and an edgeedge with one LiO4 trigonal pyramid. The corner-sharing octahedral tilt angles are 31°. There are a spread of Ti–O bond distances ranging from 1.78–2.26 Å. In the third Ti4+ site, Ti4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ti–O bond distances ranging from 1.76–2.32 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three Li1+ and two Ti4+ atoms. In the second O2- site, O2- is bonded in a T-shaped geometry to one Li1+ and two Ti4+ atoms. In the third O2- site, O2- is bonded to four Li1+ and one Ti4+ atom to form OLi4Ti trigonal bipyramids that share corners with two equivalent OLi4Ti trigonal bipyramids, a cornercorner with one OTi4 trigonal pyramid, and edges with two equivalent OLi4Ti trigonal bipyramids. In the fourth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+ and two Ti4+ atoms. In the fifth O2- site, O2- is bonded to four Ti4+ atoms to form distorted OTi4 trigonal pyramids that share a cornercorner with one OLi4Ti trigonal bipyramid and corners with two equivalent OTi4 trigonal pyramids. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ti4+ atoms. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to four Ti4+ atoms.« less
