Polynuclear complex formation of trivalent lanthanides by 5-sulfosalicylate in an aqueous system-potentiometric, 1H NMR, and TRLIFS studies

The coordination geometry of poly-nuclear Ln(III)-5-sulfosalicylate complexes in aqueous system has been determined using potentiometry, 1H NMR and TRLIFS (time resolved laser-induced fluorescence spectroscopy).
