摘要： 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].

Abstract: The tri-substituted heteropolyanions with Keggin structure, α-and β-, are two important geometricaLIsomers. 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 geometricaLIsomers 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.

Key words: Distinguishing geometricaLIsomers, tri-Substituted heteropolyanion, Keggin structure
