Title: Materials Data on NaNbO3 by Materials Project

Abstract

NaNbO3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 12-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.42–2.90 Å. In the second Na1+ site, Na1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Na–O bond distances ranging from 2.49–3.08 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 13–18°. There are a spread of Nb–O bond distances ranging from 2.00–2.02 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 16–29°. There are a spread of Nb–O bond distances ranging from 1.91–2.16 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Na1+ and two equivalent Nb5+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to threemore » Na1+ and two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Na1+ and two equivalent Nb5+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Na1+ and two equivalent Nb5+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Na1+ and two Nb5+ atoms.« less
