Abstract
Abstract Reaction of 4-aminoantipyrine with 2-mercaptobenzoic acid afforded a proton transfer derivative, 1-phenyl-2,3-dimethyl-5-oxo-1,2-dihydro-1 H -pyrazol-4-ammonium 2[(2-carboxyphenyl) disulfanyl]benzoate, (HAAP + ⋅HTBA − ), via the oxidation of 2-mercaptobenzoic acid into 2,2′-dithiobis(benzoic acid). The compound has been characterized on the basis of elemental analysis, IR, 1 H and 13 C NMR and mass spectral data. The infrared spectrum suggests the existence of an ion-pair compound, which is further established by the single crystal X-ray analysis to be an extended 1D supramolecular chain network extending along ‘b’ cell direction. The compound shows good thermal stability.
