Materials Data on RbPH4O5 by Materials Project
RbPH4O5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to one H1+ and eight O2- atoms. The Rb–H bond length is 3.13 Å. There are a spread of Rb–O bond distances ranging from 2.91–3.29 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.51–1.60 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.63 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to one Rb1+ and one O2- atom. The H–O bond length is 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.69 Å) H–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one P5+ atom. In the third O2- site, O2- is bonded in a water-like geometry to two equivalent Rb1+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Rb1+, one P5+, and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Rb1+, one P5+, and one H1+ atom.
