چکیده
In the title compound, C(17)H(18)NO(2) (+)·Cl(-)·H(2)O, a precursor to novel asymmetric catalysts, the N-containing six-membered ring of the tetra-hydro-quinolinium unit assumes a half-boat conformation. In the crystal, inter-molecular O-H⋯O, O-H⋯Cl, N-H⋯Cl and C-H⋯O hydrogen bonds and C-H⋯π inter-actions link the mol-ecules into a three-dimensional network.
