Materials Data on Rb3(SO4)2 by Materials Project

Abstract

Rb3(SO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first 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 2.93–3.24 Å. In the second Rb site, Rb is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Rb–O bond distances ranging from 3.03–3.15 Å. S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. There are four inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to three Rb and one S atom. In the second O site, O is bonded in a distorted single-bond geometry to four Rb and one S atom. In the third O site, O is bonded in a distorted single-bond geometry to three Rb and one S atom. In the fourth O site, O is bonded in a distorted single-bond geometry to four Rb and one S atom.
