Abstract

Abstract: Detailed investigation on the preparation and properties of telluratocuprate(Ⅱ,Ⅲ)complexes has been performed.In the solution of H6TeO₆/KOH,Cu(Ⅲ)complex wasobtained by adopting ozone as oxidant and a new copper(Ⅲ)compound Ba₄K[Cu(H₂TeO₆)2](OH)₄· 6H₂O was isolated.The cyclic voltammogram of _u Cu(Ⅲ)/Cu(Ⅱ)"couple in alka-line solution was described.According to the electronic spectra and Cu₂p XPS of the new Cu(Ⅲ)compound, Na4H[Cu(H₂TeO₆)₂]·17H₂O and related Cu(Ⅱ) complexes, the ligandfield parameters and the binding energies of Cu₂p3/2 for these Cu(Ⅲ)and Cu(Ⅱ)complexeswere determined.

Key words: telluratocuprate(Ⅱ, Ⅲ)complex, ozone oxidation, voltammogram, electronicspectrum, XPS
