Benzimidazolium 3,5-dihydroxybenzoate

X. Huang, J.-G. Liu and D.-J. Xu

Abstract: In the crystal structure of the title compound, C₇H₇N₂⁺·C₇H₅O₄^-, the partially overlapped arrangement and the face-to-face separation of 3.557 (7) Å suggest - stacking between parallel benzimidazolium cations, and the C-HCg angle of 173° and HCg separation of 2.64 Å (where Cg is the centroid of the benzene ring) suggest C-H stacking between the benzimidazolium cation and dihydroxybenzoate anion. Classical N-HO and O-HO and weak C-HO hydrogen bonds consolidate the crystal structure.
