Crystallisation of 1,2-dimethylimidazole, and 1-methylimidazole with organic acids.

ABSTRACT: Crystals of 1-methylimidazole and 1,2-dimethylimidazole with glutaric and succinic acids are described. The crystal structure including 1,2-dimethylimidazole and glutaric acid, has been reported previously, but the molecular salt of 1-methylimidazole with succinic acid were characterized for the first time in this study. The structures were characterised by using X-ray crystallography, intermolecular hydrogen bond geometry, energy, and topology. In both crystal structures the molecules are linked by N-H….O and C-H….O hydrogen bonds. Using Hirshfeld surface analyses and quantum-theoretical calculations, we provide insights into the intermolecular interactions, revealing dependencies on the chemical environment. The result of the interaction region indicator (IRI) analysis indicated that suc
