Materials Data on Rb2PH3SeO8 by Materials Project

Rb2PH3SeO8 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.43 Å. In the second 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 2.91–3.24 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.50–1.60 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.21 Å. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.61 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.58 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.22 Å. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.66–1.72 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two Rb1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Rb1+, one P5+, and one H1+ 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 H1+, and one Se6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Rb1+, one H1+, and one Se6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one H1+, and one Se6+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+ and one Se6+ atom.
