Materials Data on Rb3(SeO4)2 by Materials Project

Abstract

Rb3(SeO4)2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded in a 12-coordinate geometry to six equivalent O atoms. All Rb–O bond lengths are 3.00 Å. In the second Rb site, Rb is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Rb–O bond distances ranging from 3.01–3.15 Å. Se is bonded in a tetrahedral geometry to four O atoms. There is three shorter (1.67 Å) and one longer (1.69 Å) Se–O bond length. There are two inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to four Rb and one Se atom. In the second O site, O is bonded in a distorted single-bond geometry to one Rb and one Se atom.
