Materials Data on RbVPHO6 by Materials Project
RbVPHO6 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.95–3.53 Å. V5+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent PO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.63–1.97 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent VO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.53 Å) H–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Rb1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+ and two equivalent V5+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one V5+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to two equivalent Rb1+ and one V5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one P5+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one V5+, and one P5+ atom.
