Materials Data on Cs2VCl5O4 by Materials Project

Abstract

Cs2VO4Cl5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Cs is bonded in a 8-coordinate geometry to eight Cl atoms. There are a spread of Cs–Cl bond distances ranging from 3.34–3.67 Å. V is bonded in an octahedral geometry to four equivalent O and two equivalent Cl atoms. All V–O bond lengths are 1.84 Å. Both V–Cl bond lengths are 2.36 Å. O is bonded in a single-bond geometry to one V atom. There are three inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted single-bond geometry to three equivalent Cs and one V atom. In the second Cl site, Cl is bonded in a see-saw-like geometry to four equivalent Cs atoms. In the third Cl site, Cl is bonded in a linear geometry to two equivalent Cs atoms.
