The preparation and X-ray crystal structures of Br2S+SSBr(AsF6–) and Br2Se+SeSeBr(AsF6–)
Abstract
Reactions of stoicheiometric quantities of sulphur or selenium, bromine, and arsenic pentafluoride in liquid SO2 lead to the quantitative syntheses of crystalline Br2M+MMBr(AsF6–), (M = S, Se), the structures of which were determined by single crystal X-ray diffraction.
