organic compounds
The title compound, C13H13N5·1.5H2O, was synthesized by the reaction of 2,6-bis(bromomethyl)pyridine with imidazole. The asymmetric unit contains two crystallographically independent 2,6-bis(1H-imidazol-1-ylmethyl)pyridine molecules and three water molecules. The crystal packing is stabilized by O—HO and O—HN hydrogen-bond interactions.
