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 spectively.Furthermore,their coordination mechanism,spectral properties and probable molecular structures were also discussed.
