Materials Data on NaNO3 by Materials Project

NaNO3 is Calcite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted corner-sharing NaO6 octahedra. The corner-sharing octahedra tilt angles range from 62–67°. There are a spread of Na–O bond distances ranging from 2.44–2.64 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 2.43–2.79 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form corner-sharing NaO6 octahedra. The corner-sharing octahedra tilt angles range from 62–66°. There are a spread of Na–O bond distances ranging from 2.32–2.47 Å. In the fourth Na1+ site, Na1+ is bonded to six O2- atoms to form corner-sharing NaO6 octahedra. The corner-sharing octahedra tilt angles range from 64–67°. There are a spread of Na–O bond distances ranging from 2.39–2.52 Å. There are four inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.26 Å) and two longer (1.27 Å) N–O bond length. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. All N–O bond lengths are 1.27 Å. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. All N–O bond lengths are 1.27 Å. In the fourth N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. All N–O bond lengths are 1.27 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Na1+ and one N5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Na1+ and one N5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Na1+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two Na1+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two Na1+ and one N5+ atom.
