Contribution to the study of the complexes bis(dihydrogen tellurato)cuprate(III) and argentate(III), bis(hydrogen periodato)cuprate(III) and argentate(III)

The synthesis and characteristics of copper(III) and silver(III) complexes of tellurates and periodates are described. Chemical analysis, I.R. spectra and conductimetric measurements were used to determine the formulae of these anionic complexes, which were found to be: [Cu(H2TeO6)2]5−; [Cu(HIO6)2]5−; [Ag(H2TeO6)2]5− and [Ag(HIO6)2]5−.
