Crystal structure and Hirshfeld surface analysis and of 2-ammoniumylmethyl-1H-benzimidazol-3-ium chloride mononydrate

Abstract

The asymmetric unit of the title compound, C8H11N32+ center dot 2Cl(- )center dot H2O, contains three organic cations, six chloride anions and three water molecules of crystallization, which are connected by extensive hydrogen-bonding interactions into a threedimensional supramolecular architecture. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H center dot center dot center dot H (37.4%), Cl center dot center dot center dot H/H center dot center dot center dot Cl (35.5%), C center dot center dot center dot H/H center dot center dot center dot C (9.5%) and C center dot center dot center dot C (6.9%) interactions.
