Materials Data on CsSb2F7 by Materials Project

Abstract

CsSb2F7 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Cs–F bond distances ranging from 3.12–3.28 Å. Sb3+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of Sb–F bond distances ranging from 1.99–2.70 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one Cs1+ and one Sb3+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Sb3+ atoms. In the third F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Sb3+ atom. In the fourth F1- site, F1- is bonded in a linear geometry to two equivalent Sb3+ atoms.
