title: Spectrophotometric study of the complex formation of 3-(1-naphthyl)-2-mercaptopropenoic acid with nickel(II), palladium(II) and hydrogen ions.
abstract: The equilibria between 3-(1-naphthyl)-2-mercaptopropenoic acid (H(2)NMP) and nickel, palladium and hydrogen ions at 25 degrees in aqueous 0.1 M NaClO(4) solution containing 1-2% ethanol have been studied spectrophotometrically. Protonation constants for the ligand and formation constants for the complexes Ni(NMP), Ni(NMP)(2-)(2), Pd(NMP) and Pd(NMP)(2-)(2), refined by the SQUAD program, are reported.
