Two proton transfer hydrogen-bonded complexes of 5-sulfosalicylic acid (3-carboxy-4-hydroxybenzenesulfonic acid, 5-SSA) with the aromatic amides: nicotinamide (NA) and isonicotinamide (INA), are characterized by X-ray diffraction and spectroscopic studies. In the crystal structures of nicotinamidium 3-carboxy-4-hydroxybenzenesulfonate, 1, and isonicotinamidium 3-carboxy-4-hydroxybenzenesulfonate monohydrate, 2, the ions are linked into three dimensional frameworks by a combination of O-H?O, N-H?O and C-H?O hydrogen bonds and cation-anion π-π stacking interactions. The hydrogen-bonding behavior of the pyridine N atom is different in the two crystals, bonding to a sulfonate O atom of anion in 2 but to a carbonyl O atom of cation in 1. The complex 1 shows relatively efficient second harmonic frequency generation.
