| Abstract: 15 new lanthanide(Ⅲ) complexes with chiral crown ether (+）-12-ethyl-1,4,7,10-tetra-oza-13-azacyclo-pentadecane were prepared. Their formulae were determined to be Ln(NO3)3·L(+)·H2O(Ln=La、Ce、Pr、Nd); Ln(SCN)3·L(+)·H2O(Ln=La、 Pr、Nd、 Sm、 Eu、Gd-Er、Yb) respectively by elemental analysis. The physical and chemical properties of the complexes were studied with conductance, IR and absorption spectra. The specific rotatory power and CD spectrum of the complex Pr(SCN)3·L(+)·H2O were also measured and a brief discussion has been made. |
