| Abstract: Nine novel lanthanide complexes with β-amino acid Schiff base-N-salicylidene-β-alanine(H2L)--have been synthesized in the presence of triethylamine. The complexes have been characterized by elemental analysis, molar conductance, TG-DTA, UV, IR and NMR measurements. Their formulae are ［Ln2(HL)3NO3］(NO3)2·nH2O, (Ln=La, Pr, Nd, Sm, Gd, n=2; Ln=Tb, Er, Yb, Y,n=4), where the Gd and Y complexes belong to the lighter and heavier Ln groups respectively. All the water molecules are uncoordinated. Experimental results show that the obtained complexes have catalytic activity for the polymerization of methyl methacrylate(MMA). |
