Title: Materials Data on Li2CeO3 by Materials Project

Abstract

Li2CeO3 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form LiO5 trigonal bipyramids that share corners with two equivalent CeO6 octahedra, corners with six equivalent LiO5 trigonal bipyramids, edges with four equivalent CeO6 octahedra, and edges with three equivalent LiO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 52°. There are a spread of Li–O bond distances ranging from 1.93–2.33 Å. Ce4+ is bonded to six O2- atoms to form CeO6 octahedra that share corners with two equivalent CeO6 octahedra, corners with four equivalent LiO5 trigonal bipyramids, edges with two equivalent CeO6 octahedra, and edges with eight equivalent LiO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 0°. All Ce–O bond lengths are 2.25 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Li1+ and two equivalent Ce4+ atoms to form OLi4Ce2 octahedra that share corners with two equivalent OLi4Ce2 octahedra, corners with four equivalent OLi3Ce2 trigonal bipyramids, edges with two equivalent OLi4Ce2 octahedra, and edges with eight equivalent OLi3Ce2 trigonal bipyramids.
