Materials Data on Li3Ti8O16 by Materials Project
Li3Ti8O16 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Pmmn 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 LiO4 tetrahedra that share corners with twelve TiO6 octahedra. The corner-sharing octahedra tilt angles range from 58–60°. There are two shorter (2.01 Å) and two longer (2.03 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with twelve TiO6 octahedra. The corner-sharing octahedra tilt angles range from 58–60°. There are three shorter (2.02 Å) and one longer (2.03 Å) Li–O bond lengths. There are four inequivalent Ti+3.62+ sites. In the first Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with five LiO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.95–2.05 Å. In the second Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with five LiO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.95–2.04 Å. In the third Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four LiO4 tetrahedra and edges with six TiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.98–2.03 Å. In the fourth Ti+3.62+ site, Ti+3.62+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four LiO4 tetrahedra and edges with six TiO6 octahedra. There are two shorter (1.99 Å) and four longer (2.02 Å) Ti–O bond lengths. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded to one Li1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing OLiTi3 trigonal pyramids. In the second O2- site, O2- is bonded to one Li1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing OLiTi3 trigonal pyramids. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to three Ti+3.62+ atoms. In the fourth O2- site, O2- is bonded to one Li1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing OLiTi3 trigonal pyramids. In the fifth O2- site, O2- is bonded to one Li1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing OLiTi3 trigonal pyramids. In the sixth O2- site, O2- is bonded to one Li1+ and three Ti+3.62+ atoms to form a mixture of distorted edge and corner-sharing OLiTi3 trigonal pyramids. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ti+3.62+ atoms.
