The structure of the title compound, C₁₉H₁₈NO₂⁺·C₇H₇O₄S^-, was determined by a single crystal X-ray diffraction technique. The compound crystallizes in monoclinic space group Pc with a = 10.9895(1), b = 7.1363(1), c = 15.6341(2)Å, β = 110.300(1)°, Z = 2, V = 1149.94(2)ų and D_x = 1.385 g cm^-3. In the crystal packing, the cations and anions are individually linked into alternate layers parallel to the bc plane by weak C-H…O interactions; these ionic layers are interconnected through an intermolecular O-H…O hydrogen bond and weak intermolecular C-H…O interactions, forming a three-dimensional network. The molecular packing is stabilized by an O-H…O hydrogen bond and weak C-H…O interactions. The second harmonic generation (SHG) efficiency of the compound is about 0.45-times that of urea.
