AbstractThe title compound, C18H23N2O2 +·Cl-, crystallizes with two independent cations and anions per cell. Each cation has twofold rotational disorder about the linking vinyl groups but with unequal occupancies [0.963(5):0.037(5) and 0.860(8):0.140(8)]. The two independent cations are close to being related by an inversion centre but the data does not support the expected centrosymmetric space-group assignment. The conclusion is that the differing rotational disorder has lead to an overall non-centrosymmetric lattice. In the crystal, the molecules pack in layers parallel to (133) and (1̄3-3̄), chain-linked with motif C 1 2(7) by the dihydroxypropyl O-H.Cl.H-O hydrogen bonds. Other lattice binding is provided by O-H.Cl, C-H.Cl and C-H.N interactions.
