稀土二乙基取代双氮杂18-C-6配合物的合成与表征

PREPARATION AND CHARACTERIZATION OF RARE EARTH(III) ISOTHIOCYANATE COMPLEXES WITH DIETHYL-SUBSTITUTED DIAZA 18-C-6

以2－氨基丁醇、二氯乙烷、多甘醇、对甲苯磺酰氯为原料合成了一个新配体12，17－二乙基－1，4，7，10－四氧杂－13，16－二氮杂环十八烷（L）．在无水乙醇中合成出7个稀土硫氰酸盐－冠醚配合物．经元素分析确定其组成分别为Ln（SCN）3·L·H2O（Ln＝Pr，Nd，Eu，Gd，Tb，Dy），Y（SCN）3·L·3H2O．通过IR，UV－Vis和电导测定等方法讨论了配合物的配位结构和性质．

With the starting materials 2- amino- butanol, dichloroethane, polyglycol and p- toluenesulfonyl chloride, a new ligand 12, 17- diethyl- 1, 4, 7, 10-tetraoxa- 13, 16- diaza 18- crown- 6 is synthesized. Seven new rare earth(III) isothiocyanate complexes with the ligand are prepared in absolute alcohol with the presense of dehydrating agent triethylorthoformate respectively. Elemental analysis shows that they have formulae RE(SCN)3·L·H2O (RE=Pr,Nd, Eu, Gd, Tb, Dy), Y(SCN)3·L·3H2O. Their properties are studied with UV, IR absorption spectroscopy and conductometry. Their coordination structres are also discussed.
