一、前言 具有环状空腔结构特征的冠醚类化合物,因其特殊的配合性质已日益引起人们的注意。近十余年来,“有关锕系元素冠醚配合物的研究虽有不少报道,但以往的研究工作所涉及到的主要是一些含醚氧原子数目小于7的冠醚。到目前为止,有关钍与含醚氧原子数目在7个以上的大空腔冠醚的固体配合物文献中尚未见报道。为此,我们对硝酸钍与二苯并-24-冠-8(简称DB24C8)的固态配合物的合成及性质进行了研究。
I. INTRODUCTION Crown ethers with ring-like cavity structure have attracted more and more attention because of their special coordination properties. In the past ten years or more, "Although there are many reports on the studies of actinide crown ether complexes, the main research work involved in the past are mainly some crown ethers with fewer than 7 oxygen atoms in the ether. Up to now, The literature about solid complexes of thorium and crown ether containing more than 7 oxygen atoms in ether has not been reported yet.Therefore, the solid state of thorium nitrate and dibenzo-24-crown-8 (DB24C8) The synthesis and properties of the complexes were studied.
