单N-乙酸取代O2N2大环配体及其稀土配合物的合成与表征

         

摘要

A series of new rare earth complexes LnL(NO3)2·2H2O(Ln = La, Pr, Nd, Sm, Eu, Gd, Dy, Yb; L = 1, 2-diaza-3, 4: 9, 10-dibenzo-5, 8-dioxyacyclopentadecane-N-acetic ion)were prepared. The complexes were characterized by elemental analysis, ICP method, IR spectra, 1H NMR and Molar conductance. It was found that the ether oxygen, carboxy oxygen and nitrogen atoms of the ligand are coordinated to the metal ion, as well as a free nitrate and coordianted nitrate ion in the complex.
