摘要： 首次合成了一种新的1.2-双(3,4:9,10-二苯并-5,8-二氧杂-1,12-二氮杂环十五烷-N-乙酸)乙烷大环配体,制备了它的8个镧系元素(La,Pr,Nd,Sm,EU,Gd,Dy,Yb)配合物,用红外光谱、元素分析、核磁共振谱及电导等方法进行了表征,讨论了可能的配位情况。

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
