摘要
苯并冠醚对碱金属、碱土金属及稀土金属离子具有特殊的配位能力,但它们与溶剂化能量较大的“软酸”过渡金属离子配位较难。通过在冠醚苯环上引入吸电子取代基团减弱冠醚的碱性,是这类过渡金属大环配合物研究的一个重要方面。从模拟金属蛋白中铜(Ⅱ)离子的位置看,铜(Ⅱ)离子冠醚配合物的研究具有一定的意义。本文在过去工作的基础上,合成了高氯酸铜与4′-溴苯并-15-冠-5(L_A)及4′,5′-二溴苯并-15-冠-5(L_R)两种新配合物,并研究了它们的有关物理、化学性质。
In this paper, the two coordination compounds of copper perchlorate with 4'-bromo(or 4',5'-dibromo)-benzo=15-crown-5 have been prepared in acetone medium, the composition of the new coordination compounds have been determined as Cu(ClO_4)_2·L·3H_2O(L=4'-bromobenzo-15-crown-5 or 4', 5'-dibromo-benzo-15-crown-5), the IR, UV, TG-DTA,X-ray powder diffraction analysis and molar conductance of these coordination compounds have also been studied. It shows that coordination number of the coordination compounds is 9.
