自Pederson发现冠醚以来,已合成了许多冠醚和金属离子的络合物。这些络合物中的金属离子主要是碱金属、碱土金属离子,关于过渡元素与冠醚络合物的报道不多。为了揭示这类化合物的结构特性,我们用X射线单晶衍射法测定了(VOCl_2·4H_2O)(18-冠-6)的晶体结构,以对冠醚和矾的结合方式进行研究。
Since the discovery of crown ether by Pederson, many crown ether and metal ion complexes have been synthesized. The metal ions in these complexes are mainly alkali metal and alkaline earth metal ions, and few reports on transition elements and crown ether complexes. In order to reveal the structural characteristics of these compounds, the crystal structure of (VOCl_2 · 4H_2O) (18-crown-6) was determined by X-ray single crystal diffraction and the combination of crown ether and alum was studied.
