Abstract

Li9Ti5(SiO8)2 is Caswellsilverite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one LiO6 octahedra, corners with two equivalent SiO6 octahedra, corners with three TiO6 octahedra, an edgeedge with one TiO6 octahedra, edges with three equivalent SiO6 octahedra, and edges with eight LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–17°. There are a spread of Li–O bond distances ranging from 2.05–2.32 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share a cornercorner with one LiO6 octahedra, corners with two equivalent SiO6 octahedra, corners with three TiO6 octahedra, edges with two equivalent SiO6 octahedra, edges with three TiO6 octahedra, and edges with seven LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–15°. There are a spread of Li–O bond distances ranging from 2.05–2.31 Å.
