Materials Data on Li2Ti3NbO8 by Materials Project
Li2Ti3NbO8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent NbO6 octahedra and corners with nine equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 57–60°. There are three shorter (2.02 Å) and one longer (2.05 Å) Li–O bond lengths. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent NbO6 octahedra, and edges with four equivalent TiO6 octahedra. All Ti–O bond lengths are 2.03 Å. Nb2+ is bonded to six equivalent O2- atoms to form NbO6 octahedra that share corners with six equivalent LiO4 tetrahedra and edges with six equivalent TiO6 octahedra. All Nb–O bond lengths are 2.09 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one Li1+ and three equivalent Ti4+ atoms to form distorted corner-sharing OLiTi3 trigonal pyramids. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, two equivalent Ti4+, and one Nb2+ atom.
