Title: Materials Data on Li4Ti5Nb3O16 by Materials Project

Abstract

Li4Ti5Nb3O16 is Spinel-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with five NbO6 octahedra and corners with seven TiO6 octahedra. The corner-sharing octahedra tilt angles range from 52–61°. There are a spread of Li–O bond distances ranging from 1.94–1.99 Å. In the second Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.80–2.05 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one NbO6 octahedra, corners with five TiO6 octahedra, an edgeedge with one TiO6 octahedra, and edges with two equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 57–62°. There are a spread of Li–O bond distances ranging from 1.80–2.04 Å. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four NbO6 octahedra and corners with eight TiO6 octahedra. The corner-sharing octahedra tilt angles range from 41–63°.more » There are a spread of Li–O bond distances ranging from 1.88–2.02 Å. There are four inequivalent Ti4+ sites.
