Materials Data on RbPO3 by Materials Project

Abstract

RbPO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.88–3.36 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.93–3.39 Å. In the third Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.83–3.36 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.50 Å) and one longer (1.51 Å) P–O bond length. In the second P5+ site, P5+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.50 Å) and one longer (1.51 Å) P–O bond length. In the third P5+ site, P5+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.50 Å) and one longer (1.51 Å) P–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+ and one O2- atom. The O–O bond length is 1.26 Å. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to four Rb1+ and one O2- atom. The O–O bond length is 2.58 Å. In the seventh O2- site, O2- is bonded in a single-bond geometry to two Rb1+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Rb1+ and two O2- atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one P5+ atom.
