Tetraperoxotantalates with organic cations as well as an oligomeric peroxopolytantalate were prepared for the first time by perhydrolysis of tantalum(V)ethoxide, Ta(OC2H5)5, in the presence of bases. Guanidinium, tert-butylammonium and cyclohexylammonium salts of tetraperoxotantalic acid crystallize from ethanol as relatively stable compounds. The cell constants of these compounds are determined. By perhydrolysis of the ester in petroleum ether the tert-butylammonium salt of a peroxododecantalic acid was obtained. The molecular mass of this water soluble compound was determined with the ultracentrifuge.
