文摘

Crystallization of 2,2′-bipyridine from aqueous solution containing sulfur(IV) oxide afforded clathrates with the composition (bipy)_k · (SO₂)_m · (H₂O)_n. X-Ray amorphous guest SO₂ molecules occupy voids in the crystal lattice of 2,2′-bipyridine without distortion of its structure. The isolated compounds were characterized by elemental analyses, X-ray diffraction data, and IR, NMR, and mass spectra.
