Abstract: The synthesis and characterization of a new bis-N-functionalized diaza-dioxa maeroeycle 1,2-his(1, 12-diaza-3, 4:9,10-dibenzo-5, 8-dioxaeyclopentadeeane-N-aeetie aeid) ethane (H2L2) are reported. Eight lanthanide (La, Pr, Nd, Sm, Eu, Gd, Dy, Yb) complexes with this ligand have been prepared in methanol solution by the reaction of H2L2 with rare earth nitrate respectively. These complexes have a general formula of Ln2L2(NO3)4·nH2O. Their coordination properties are discussed.

Key words: bis-N-acetic acid substituted diaza-dioxa macrocycle, rare earth, complex, synthesis
