SYNTHESIS, CHARACTERIZATION AND CD SPECTRA OF COMPLEXES OF LANTHANIDES NITRATES, THIOCYANIDES WITH CHIRAL CROWN ETHER (+)12ETHYL1,4,7,10TETRAOZA13AZACYCLOPENTADECANE

合成了共１５个未见文献报道的三价镧系离子与手性氮杂冠醚（＋）－１２－乙基－１，４，７，１０－四氧杂－１３－氮杂环十五烷（以下以Ｌ（＋）表示）的配合物Ｌｎ（ＮＯ３）３·Ｌ（＋）·Ｈ２Ｏ（Ｌｎ＝Ｌａ、Ｃｅ、Ｐｒ、Ｎｄ）；Ｌｎ（ＳＣＮ）３·Ｌ（＋）·Ｈ２Ｏ（Ｌｎ＝Ｌａ、Ｐｒ、Ｎｄ、Ｓｍ、Ｅｕ、Ｇｄ－Ｅｒ、Ｙｂ）。对所合成配合物进行了元素分析、电导、红外、可见吸收光谱、比旋光度和圆二色谱（ＣＤ谱）的测试，并对配合物的有关物理化学性质进行了讨论。

?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(NO 3) 3·L(+)·H 2O(Ln=La Ce Pr Nd); Ln(SCN) 3·L(+)·H 2O(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(+)·H 2O were also measured and a brief discussion has been made.
