【Abstract】 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.\=更多还原
