摘要: 冠醚对稀土苦味酸盐的萃取研究已有较多报道[1,2],但与萃取过程密切相关的冠醚与稀土苦味酸盐配合物的研究却报道不多[3-5],本工作合成了文献中尚未见报道的轻稀土苦味酸盐RE(Pic)3(RE=La、Pr、Nd、Sm、Eu和Gd)与18-冠-6(18C6)的固体配合物并研究其组成和性质。

Abstract: Six new solid complexes of the light lanthanide picrate with 18-crown-6 ether have beensynthesized in ethanol solution.The complexes are formularized to be RE(Pic)3·18C6·H2O,(RE = La, Pr, Nd, Sm, Eu, and Gd, Pic = picrate).The compositions and structures of thecomplexes have been characterized by elemental analyses, molar conductance measurements,IR spectra, 1H-NMR spectra and X-ray powder diffractometry.

Key words: 18-crown-6 ether, picrate, light lanthanide, complex, synthesis
