Materials Data on Rb3PO4 by Materials Project
Rb3PO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two 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 2.77–3.06 Å. In the second 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 2.91–3.29 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. All P–O bond lengths are 1.57 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to five Rb1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to five Rb1+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to five Rb1+ and one P5+ atom.
