Abstract

NaNbO3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of Na–O bond distances ranging from 2.38–2.91 Å. In the second Na1+ site, Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.47–2.69 Å. Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 18–30°. There are a spread of Nb–O bond distances ranging from 1.90–2.19 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Na1+ and two equivalent Nb5+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+ and two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+ and two equivalent Nb5+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to three Na1+ and two equivalent Nb5+ atoms.
