Abstract

(CF2)2AsSOF5SO2 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of eight difluoromethane molecules, four sulfur dioxide molecules, and four AsSOF5 clusters. In each AsSOF5 cluster, As5+ is bonded in an octahedral geometry to one O2- and five F1- atoms. The As–O bond length is 2.02 Å. There are a spread of As–F bond distances ranging from 1.74–1.77 Å. S1+ is bonded in a single-bond geometry to one O2- atom. The S–O bond length is 1.55 Å. O2- is bonded in a distorted bent 120 degrees geometry to one As5+ and one S1+ atom. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As5+ atom.
