Artykuł
A potentiometric and spectroscopic study has been carried out on the copper(II) complexes formed by 2,x-dihydroxybenzoic acids (x = 4, 5 or 6) in aqueous solution. It has been found that, in the low pH range, the ligands coordinate through the carboxylate group. At above pH 5 the major species are chelated complexes in which one or two ligands bind the metal ion through the carboxylate and adjacent phenolate groups. The results are compared to earlier literature data available for copper(II) dihydroxybenzoate and salicylate complexes.
