Materials Data on RbNO3 by Materials Project

Abstract

RbNO3 crystallizes in the trigonal P3_2 space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.85–3.16 Å. In the second Rb1+ site, Rb1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Rb–O bond distances ranging from 2.81–3.19 Å. In the third Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.87–3.30 Å. There are three inequivalent N5+ sites. In the first 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 second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.26–1.28 Å. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.26 Å) and one longer (1.28 Å) N–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+ and one N5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one N5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+ and one N5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one N5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one N5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Rb1+ and one N5+ atom.
