Materials Data on LiTiO2 by Materials Project

Abstract

LiTiO2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Li1+ is bonded to six equivalent O2- atoms to form LiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four equivalent LiO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with eight equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.04 Å) and two longer (2.12 Å) Li–O bond lengths. Ti3+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent TiO6 octahedra, edges with four equivalent TiO6 octahedra, and edges with eight equivalent LiO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.04 Å) and two longer (2.12 Å) Ti–O bond lengths. O2- is bonded to three equivalent Li1+ and three equivalent Ti3+ atoms to form a mixture of corner and edge-sharing OLi3Ti3 octahedra. The corner-sharing octahedral tilt angles are 0°.
