Materials Data on Rb2WO4 by Materials Project

Abstract

Rb2WO4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.86–3.41 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.41 Å. W6+ is bonded in a tetrahedral geometry to four O2- atoms. All W–O bond lengths are 1.82 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one W6+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one W6+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to four Rb1+ and one W6+ atom.
