Six novel rare earth complexes with noncyclic polyether- glycylglycine Schiff base (TAGLGL) have been synthesized with "step by step" method. They were confiremd by elemental analysis, IR, etc. and their formulas were established as [Ln3(TAGLGL)(NO3)7]·4H2O(Ln=La, Nd, Sm, Gd, Yb, Y). Owing to introducing a dipeptide bond with C=N and HN—C=O groups in the ligand, 1^H NMR and solid high resolution 13^C NMR with CPMAS and TOSS techniques and EPR spectra were used for elucidating the crystal field stregth, the symmetry in the obtained Gd(Ⅲ) complex andthe coordination of the donor atoms of the ligand with rare earth elements.
