In 1,3-dimethyl-2-imidazolidinone (DMEU) as solvent, pentafluoropyridine reacts with PhSNa to give an essentially quantitative yield of pentakis(phenylthio)pyridine (1); however, analogous reaction with pentachloropyridine leads to the unexpected co-formation of the title compound (2), a new host whose crystal structure has been elucidated by X-ray methods for both the unsolvated crystal and for the chlorobenzene inclusion compound.
