锕系元素冠醚配合物中,研究得最多的是铀酰与冠醚形成的配合物,以往的工作主要集中在配合物的合成及性质研究方面,而对其结构很少研究。迄今为止,只测定过硝酸铀酰与18-冠-6配合物的晶体结构,铀酰与其它种类冠醚形成的配合物的结构文献中还未见报道。我们在乙腈溶液中培养出硝酸铀酰与苯并-15-冠-5的配合物[UO_2(NO_3)_2(H_2O)_2]·(B15C5)单晶,并研究该配合物的晶体及分子结构。
Actinides crown ether complex, the most studied is the formation of uranyl and crown ether complexes, the previous work mainly focused on the synthesis and properties of complexes, and its structure rarely studied. To date, only the crystal structure of the complex of uranyl nitrate and 18-crown-6 has been determined, and the structure of the complex formed between uranyl and other crown ethers has not been reported yet. In this study, we synthesized single crystal of [UO_2 (NO_3) _2 (H_2O) _2] · (B15C5) with uranyl nitrate and benzo-15-crown-5 in acetonitrile solution and investigated the crystal and molecular structure of the complex .
