Cyclo-octasulphur as a ligand; preparation and X-ray crystal structure of [Ag(S8)2]AsF6

Abstract

Reaction of AgAsF6 with S8 in liquid sulphur dioxide leads to [Ag(S8)2]AsF6, which contains cyclo-octasulphur ligands; the X-ray structure shows that the silver atoms achive distorted four-co-ordination by 1,3-linkages to two S8 rings.
