Materials Data on RbSO3F by Materials Project

Abstract

RbSO3F crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to seven O2- and three equivalent F1- atoms. There are a spread of Rb–O bond distances ranging from 3.01–3.17 Å. There are one shorter (3.11 Å) and two longer (3.41 Å) Rb–F bond lengths. S6+ is bonded in a tetrahedral geometry to three O2- and one F1- atom. There is one shorter (1.45 Å) and two longer (1.46 Å) S–O bond length. The S–F bond length is 1.66 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Rb1+ and one S6+ atom. F1- is bonded in a distorted single-bond geometry to three equivalent Rb1+ and one S6+ atom.
