Moustafa, M. Zaky, N. El-Khososy] Synthese und Charakterisierung einiger Lanthaniden(III)-Chelate von Schaffersäure-Azofarbstoffen Summary: A series of trivalent lanthanide chelates of the type [Ln(PHNSA) (H2O) n ] (2 Cl) (whereLn 3+=Pr, Nd, Sm, Eu, Gd, Dy, Er, Yb or Lu;PHNSA=2-(X)-phenylazo-2-hydroxynaphthalene-6-sulphonic acid;X=H, Cl, OCH3, CH3 and SO3H) have been synthesized and characterized by elemental and thermal analysis, molar conductance, IR,1H NMR (for diamagnetic complexes), electronic spectra and magnetic susceptibility measurements. IR data along with those of the1H NMR unequivocally proved that the coordination of the ligands to the metal ions took place in a bidentate fashion through the oxygen of the hydroxyl group and the nitrogen of the azo group. The magnetic moment values showed little deviation from Van Vleck values.
