摘要： 在H6TeO6/KOH水溶液中以臭氧为氧化剂,将二价铜化合物氧化成三价铜化合物,并获得一个新的三价铜化合物Ba4K[Cu(H2TeO6)2](OH)4·6H2O;描述了碱性溶液中"Cu(Ⅲ)/Cu(Ⅱ)"循环伏安图.对铜(Ⅲ)化合物,Na4H[Cu(H2TeO6)2]·17H2O以及相应的铜(Ⅱ)配合物的电子光谱和Cu2pXPS进行了研究,给出了其配位场场强参数和Cu2pXPS的电子结合能.由于价态升高,光电子空穴寿命缩短,Cu2pXPS的谱峰增宽.

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
