Abstract

Potentiometric and spectroscopic results indicated that 3,4-dihydroxybenzoic acid is a very effective ligand for cupric ions and the coordination equilibria formed are relatively complicated. In dilute aqueous solutions the bidentate catechol part of the ligand studied predominates as the binding site for metal ion although the carboxyl group may also participate in the metal ion binding leading to creation of the dinuclear species. More concentrated solutions yield a trimeric complex molecule (Cu3A2) with one metal ion bound to four phenolate oxygens and two others bound to the respective carboxylates.
