S. Irrera and G. Portalone

Abstract: In the cation of the title compound, C₈H₁₁N₂O⁺·Cl^-·H₂O, the C-N bonds of the amidinium group are identical within experiemental error [1.305 (2) and 1.304 (2) Å], and its plane forms a dihedral angle of 25.83 (8)° with the phenyl ring. The ionic components are associated in the crystal into polymeric hydrogen-bonded supramolecular tapes stabilized by N-H⁺Cl^- and N-H⁺Ow intermolecular hydrogen bonds, and by Ow-HCl^- interactions.
