Abstract
The title hexaphenol (1), a direct analogue of the β-hydroquinone hexameric unit, has been prepared by six-fold demethylation of hexakis(p-methoxyphenyloxy)benzene (2) with BBr3. Host 1 forms a trigonal adduct, space group R3, a = 22.088(3), c = 12.232(3) A, containing 6 molecules of pyridine per host molecule: a detailed X-ray study of this inclusion compound reveals a true clathrate structure, the closed cages of which accommodate a small, non-stoichiometric amount of water.
