Materials Data on RbSO4 by Materials Project

Abstract

RbSO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.31 Å. S is bonded in a tetrahedral geometry to four O atoms. There is three shorter (1.49 Å) and one longer (1.50 Å) S–O bond length. There are four inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two equivalent Rb and one S atom. In the second O site, O is bonded in a distorted single-bond geometry to three equivalent Rb and one S atom. In the third O site, O is bonded in a single-bond geometry to two equivalent Rb and one S atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two equivalent Rb and one S atom.
