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

The asymmetric unit of the title hydrated salt, C(24)H(35)N(2)O(5) (+)·Cl(−)·2H(2)O, 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 the a axis [21.977 (3) Å].
