| Abstract: | The effect of acidity and equilibrium chloride ion concentration on the interaction of PdCl4
2- with cystine (H2CySS) in hydrochloric acid solutions was studied. Pd(H4CySS)Cl3+ complex was found to form at Cl–] = 1.0, 0.5, or 0.25 mol/Linthe H+] range from 0.10 to 1.00 mol/L; the relevant equilibrium constant was determined. Monodentate coordination of cystine to
palladium(II) through the sulfur atom was proposed on the basis of analysis of conditional stability constants as functions
of Cl–] and H+]. |
