Crystal structure of 2-methyl-1H-imidazol-3-ium 3,5-di-carb-oxy-benzoate.

ABSTRACT: The structure of the title salt, C₄H₇N₂ ⁺·C₉H₅O₆ ^- (1), is reported. The compound is built from a protonated 2-methyl-imidazole and a singly deprotonated trimesic acid. Detailed analysis of bond distances and angles for both ions reveals subtle differences compared with their neutral mol-ecule counterpart. Analysis of the crystal packing in compound 1 reveals the formation of undulating chains by the ions through hydrogen bonding. The chains stack along the b axis through π-π inter-actions and inter-connect with other chains in an out-of-phase arrangement along the ac plane through further hydrogen-bonding inter-actions.
