| 摘 要： | 本文研究了十六个未见文献报道的四元稀土杂多化合物的合成方法。通过元素分析和差热热重分析确定了它们的化学组成。用 IR、uv 光谱和x-射线粉末衍射对这些化合物进行了表证。结果表明它们的杂多阴离子具有Keggin 结构,而稀土元素位于杂多阴离子的外界.

| Abstract: | This paper discovers the methods of the systhesis of tetraheteropoly compounds of rare earth elements reported first time.According to the chemical analysis,their compositions were determined.The heteropoly compounds were characterized by IR, UV spectra and X-ray powder diffraction.It shows that these compounds have Keggin struction which rare elements are in the outsphere of their heteropoly anions. |
