金属冠醚配合物是近年来引起人们广泛兴趣的研究领域。这类配合物在组成上的一个重要特点就是金属离子与冠醚之间可以存在多种配比关系:(金属∶冠醚=1∶1,2∶1,3∶2,4∶3等)。在锕系元素冠醚配合物方面,以往研究得较多的是铀酰与一些含醚氧原子数目小于7的冠醚所形成的配合物。到目前为止,有关錒系元素与含醚氧原子数目在七个以上的大空腔冠醚的配合物仅有綦尤训等报道过一种2∶1型硝酸
Metal crown ether complexes are the areas of interest that have drawn widespread interest in recent years. An important feature of this kind of complex in composition is that there are many kinds of compounding relationships between metal ions and crown ether: (metal: crown ether = 1: 1, 2: 1, 3: 2, 4: 3, etc.) . In the actinide crown ether complex, the previous study is more uranyl and some ether-containing oxygen atoms less than 7 crown ether formed by the complex. So far, the actinides and ether containing oxygen atoms in more than seven large cavities crown ether complexes only Chi You Xun reported a 2: 1 type nitric acid
