Ｋｅｇｇｉｎ结构三取代的杂多化合物，α－和β－［ＳｉＷ９Ｍ３（Ｈ２Ｏ）３Ｏ３９］７－是两种重要的几何异构体［１］，它们在催化、高质子导体和抗病毒等方面有重要应用［２，３］．本文实验采用相转移方法［４～９］，首次研究了三取代Ｋｅｇｇｉｎ系列杂多化合物在...

The tri\|substituted heteropolyanions with Keggin structure, \%\|\% and \%\|\%, are two important geometrical isomers. They have promising utilizations in catalysis, high protonic conductors and \%anti\%\|vitus. The phase transformation method has been used to investigate the different microcosmic crystals, when tri\|substituted Keggin\|type heteropolyanions are dissolved in the organic solvent of benzene. The different microcosmic crystals are taken as the new method to distinguish geometrical isomers of tri\|substituted Keggin\|type heteropolyanions. This work has filled up the gaps of microcosmic crystals in doing research work containing heteropolyanions in organic solvent.\=
