[2-(3,4-Dimethoxyphenyl)ethyl](3-{N-[2-(3,4-dimethoxyphenyl)ethyl]carbamoyl}propyl)azanium chloride dihydrate

Abstract

The asymmetric unit of the title hydrated salt, C24H35N2O5+·Cl−·2H2O, contains one organic cation that has its protonation site at the amine function, one chloride anion and two lattice water molecules. In the crystal, one pair of lattice water molecules and two chloride anions form a four-membered centrosymmetric hydrogen-bond cycle. In addition, O—H...O, N—H...O and N—H...Cl hydrogen bonds involving the N—H groups, the water molecules and the C=O group are observed. As a result, a hydrogen-bonded layer parallel to (100) is formed. The thickness of such a layer corresponds to the length of theaaxis [21.977 (3) Å].
