(+)─乙基苯并氮杂15-C-5与稀土硫氰酸盐配合物的合成和表征

SYNTHESIS AND CHARACTERIZATION OF COMPLEXES RARE EARTHTHIOCYANIDESWITH CHIRALCROWN ETHER (+)ETHYL BENZO -AZA15 - C - 5

合成了RE（SCN）3·L·H2O（RE=La，Pr，Nd，Sm，Eu，Gd，Tb，Dy，Ho，Er，Yb，Y）共12个未见文献报导的3价稀土离子与氮杂手性冠醚（＋）－12-乙基-5，6苯并-1，4，7，10四氧杂-13-氮杂环十五烷（L）的配合物，对所合成配合物进行了元素分析、电导、热谱、红外光谱、可见光谱和比族光度的测试，并对配合物的有关物理化学性质进行了讨论．

12 New rare earth(Ⅲ) complexes with chiral crown ether (+) - 12-Ethyl- 5, 6- benzo - 1,4,7,10-tetra- oxa - 13 -- azacyclo- 5 - ethylene, with the formula RE(SCN)3. L. H2O(RE=La, Pr, Nd, Sm Eu, Gd,Tb, Dy, Ho, Er, Yb, Y) were prepared. Their physical andchemical properties were studied with conductance, thermal analysis, IR and visible absorptionspectra. Their specific rotatory power was also measured.
