Materials Data on RbV2SbO8 by Materials Project
RbV2SbO8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.88–3.33 Å. There are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 19–39°. There are a spread of V–O bond distances ranging from 1.64–1.81 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 32–37°. There are a spread of V–O bond distances ranging from 1.63–1.80 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six VO4 tetrahedra. All Sb–O bond lengths are 2.00 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V5+ and one Sb5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one V5+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one V5+, and one Sb5+ 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 single-bond geometry to one Rb1+ and one V5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Rb1+, one V5+, and one Sb5+ atom.
