Materials Data on RbSF5 by Materials Project

Abstract

RbSF5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to ten F1- atoms. There are a spread of Rb–F bond distances ranging from 2.96–3.33 Å. S4+ is bonded in a square pyramidal geometry to five F1- atoms. There are a spread of S–F bond distances ranging from 1.62–1.79 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to two equivalent Rb1+ and one S4+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one S4+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one S4+ atom.
