Abstract: The title compound, C₂₂H₂₇N₇·4.5H₂O, crystallizes with two molecules of 1,4-bis(benzimidazol-2-ylmethyl)-1,4,7-triazacyclononane and nine disordered water molecules in the asymmetric unit. Each triazacyclononane group exhibits an intramolecular N-HN hydrogen bond. The crystal packing is dominated by N-HO and O-HN hydrogen bonds between organic molecules and water molecules, and also between water molecules.
