Intercalation of organic molecules into vanadium(IV) benzenedicarboxylate: Adsorbate structure and selective absorption of organosulfur compounds

Article abstract of DOI:10.1002/anie.200602556

(Figure Presented) A very good host: The guest acid molecules of hydrothermally synthesized [V(O)(bdc)](H₂bdc)_0.71 (bdc = benzenedicarboxylate) are removed to give high-quality single crystals of [V(O)(bdc)] (1). On absorption of guest molecules from the liquid phase, 1 undergoes crystal-to-crystal transformations (aniline: 2; thiophene: 3; acetone: 4). Furthermore, complex 1 also selectively absorbs thiophene and dimethyl sulfide from methane.
