Materials Data on RbPO3 by Materials Project

RbPO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.29 Å. P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+ and two equivalent P5+ atoms.

Materials Data on RbPO3 by Materials Project

RbPO3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. There are four shorter (3.00 Å) and two longer (3.09 Å) Rb–O bond lengths. P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.60 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one P5+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent P5+ atoms.

Materials Data on Rb8PO3 by Materials Project

Rb8PO3 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb1+ is bonded to one P2- and three equivalent O2- atoms to form a mixture of distorted corner and edge-sharing RbPO3 tetrahedra. The Rb–P bond length is 3.28 Å. All Rb–O bond lengths are 3.08 Å. P2- is bonded in a body-centered cubic geometry to eight equivalent Rb1+ atoms. O2- is bonded in a body-centered cubic geometry to eight equivalent Rb1+ atoms.
