Title: Materials Data on Na2CeO3 by Materials Project

Abstract

Na2CeO3 is High Pressure (4-7GPa) Tellurium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are seven inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with three CeO6 octahedra, edges with four CeO6 octahedra, and edges with five NaO6 octahedra. The corner-sharing octahedra tilt angles range from 10–21°. There are a spread of Na–O bond distances ranging from 2.35–2.51 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.28–2.68 Å. In the third Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.44–2.52 Å. In the fourth Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with five CeO6 octahedra, edges with four CeO6 octahedra, and edges with five NaO6 octahedra. The corner-sharing octahedra tilt angles range from 3–11°. There are a spread of Na–O bond distances ranging from 2.33–2.57 Å.
