Abstract

Potentiometry measurements were used to investigate equilibria of the palladium(II)-prolylglycylalanylhistidine binary system. The results obtained by this method were confirmed by 1H NMR techniques in one and two dimensions. In strongly acidic solutions, pH <1.0, PdII most probably reacts simultaneously with both proline amine and one of the imidazole nitrogens (N1 and N3) to form a macrochelate structure. At higher pH deprotonated histidine amide nitrogen is co-ordinated, while further increase of the pH results in terminal carboxylate deprotonation.
