铟(Ⅲ)的碱金属卤化物与冠醚配合物的合成及表征

Synthesis and Characterization of Complexes of Indium and Alkali Metal Halide with Crown Ethers

在萃取研究过程中,合成了10种由四溴(或碘)合铟(Ⅲ)配阴离子与苯并-15-冠-5或二苯并-18-冠-6合钾(或钠)配阳离子相结合所形成的新型固体配合物。经元素分析、红外光谱及差热-热重等方法对配合物进行了表征。通过与相应的冠醚碱金属苦味酸盐配合物结构性质的对比,较合理地解释了这两类萃取体系之间存在的某些差别。

In the course of investigation on the extractions, ten novel solid complexes formed by combining the anions of tetrabromoindate(Ⅱ) or tetraiodoindate(Ⅱ) with the complex cations of potassium or sodium ion with benzo-15-crown-5 or dibenzo-18-crown-6 were synthesized. The complexes were characterized by elemental analyses, IR spectra and thermal analyses. In addition, in comparison with the relevant structural characters of the complexes of alkali metal pi-crates with crown ethers, some differences between the two types of the extraction systems were explanined reasonably.
