Abstract

Ten new rare earth complexes with Schiff base (HL) derived from phthalaldehyde with two CHO groups and lysine, which has unsymmetrical α-and ε- -NH2 groups, were synthesized and characterized by elemental analysis, TG-DTA analysis, UV Vis, IR, and 1H NMR spectra. They were confirmed to be as LnL2(NO3)•4H2O (Ln=La, Pr, Nd, Sm, Y) and LnL2(NO3)•3H2O (Ln=Gd, Tb, Dy, Er, Yb), respectively. Furthermore, their coordination mechanism, spectral properties and probable molecular structures were also discussed.
