2-(1H-Benzimidazol-2-ylsulfanyl)butanoic acid

V. Langer, J. Micová, B. Steiner and M. Koós

Abstract: The title compound, C₁₁H₁₂N₂O₂S, forms ionic crystals consisting of protonated benzimidazole cations and carboxylic acid anions, C₁₁H₁₃N₂O₂⁺·C₁₁H₁₁N₂O₂^-. In both ions, the bicyclic 1H-benzimidazole core is essentially planar. The plane of the 2-alkylsulfanyl substituent is almost coplanar with the benzimidazole plane. The three-dimensional packing is stabilized by strong intermolecular N-HO and O-HN interactions and weak C-HO intermolecular hydrogen bonds.
