摘　　要：分别从已腈和乙醚(1:1)及乙醇和乙醚(1:10)混和溶剂为介质制得了碘化钇与15-冠-5(15 C 5),18-钇-6(18 C 6)的组成为1:1(钇:冠醚)的混和物,所得配合物在高真空时稳定,置于空气中缓慢被氧化而分解。通过元素分析、摩尔电导、红外、差热-热重和X射线粉末衍射等分析该段研究了它们的有关性质,得到了一些新结果。Complexes of yttrium iodide with 15-crown-5 and with 18-crown-6, with a stoichiometry of 1: 1, have been synthesized by using acetonitrile: ether (1: 1) and ethanol: ether (1: 10) as solvent respectively. These isolated complexes are rela- tively stable under high vaccum but will decompose in atmosphere. Their proper- ties have been investigated by means of IR spectrum, stability and molar conductance, thermogravimetric and differential thermal analysis and X-ray diffraction.
