Reaction products have been isolated from “sulphur dioxide – 2,2′-bipyridine – water” and “sulphur dioxide – tribenzylamine – water – benzene” systems. Crystallization of 2,2′- bipyridine from aqueous solution containing sulfur(IV) oxide afforded clathrates with the compositions (bipy)3·(SO2)·(H2O) (1) and (bipy)2·(SO2)·(H2O)2 (2) [1]. X-Ray amorphous guest SO2 molecules occupy voids in the crystal lattice of 2,2′-bipyridine without distortion of
its structure. Van der Waals clathrate with the composition (Bz3N)3·(SO2) (3) was obtained for tribenzylamine. Only starting Bz3N was obtained from “sulphur dioxide – tribenzylamine – water – benzene” system. The isolated compounds were characterized by elemental analyses, X-ray diffraction data, and IR, NMR, and mass spectra.
