Title: Materials Data on LiLa3Ti4O12 by Materials Project

Abstract

La3LiTi4O12 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Li1+ is bonded to twelve O2- atoms to form LiO12 cuboctahedra that share corners with four equivalent LiO12 cuboctahedra, corners with eight equivalent LaO12 cuboctahedra, faces with six LaO12 cuboctahedra, and faces with eight equivalent TiO6 octahedra. There are four shorter (2.78 Å) and eight longer (2.84 Å) Li–O bond lengths. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with four equivalent LiO12 cuboctahedra, corners with eight LaO12 cuboctahedra, a faceface with one LiO12 cuboctahedra, faces with five LaO12 cuboctahedra, and faces with eight equivalent TiO6 octahedra. There are a spread of La–O bond distances ranging from 2.74–2.78 Å. In the second La3+ site, La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with twelve LaO12 cuboctahedra, faces with two equivalent LaO12 cuboctahedra, faces with four equivalent LiO12 cuboctahedra, and faces with eight equivalent TiO6 octahedra. There are four shorter (2.78 Å) and eight longer (2.79 Å) La–O bond lengths. Ti+3.50+ is bonded to six O2- atoms to form TiO6 octahedramore » that share corners with six equivalent TiO6 octahedra, faces with two equivalent LiO12 cuboctahedra, and faces with six LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–5°. There are a spread of Ti–O bond distances ranging from 1.93–2.01 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Li1+, two equivalent La3+, and two equivalent Ti+3.50+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to one Li1+, three La3+, and two equivalent Ti+3.50+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four equivalent La3+ and two equivalent Ti+3.50+ atoms.« less
