Materials Data on RbPHO3F by Materials Project
RbPHO3F crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to five O2- and three F1- atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.21 Å. There are one shorter (3.05 Å) and two longer (3.19 Å) Rb–F bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 10-coordinate geometry to one H1+, eight O2-, and one F1- atom. The Rb–H bond length is 2.98 Å. There are a spread of Rb–O bond distances ranging from 2.89–3.34 Å. The Rb–F bond length is 3.29 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to three O2- and one F1- atom. There are a spread of P–O bond distances ranging from 1.50–1.58 Å. The P–F bond length is 1.62 Å. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to three O2- and one F1- atom. There are a spread of P–O bond distances ranging from 1.50–1.59 Å. The P–F bond length is 1.62 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to one Rb1+ and two O2- atoms. There is one shorter (1.04 Å) and one longer (1.50 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.59 Å) H–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Rb1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+, one P5+, and one H1+ 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 bent 120 degrees geometry to two Rb1+, one P5+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Rb1+, one P5+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one P5+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to two equivalent Rb1+ and one P5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to two Rb1+ and one P5+ atom.
