In this paper,the cyclic voltammetric and spectroelectrochemical behaviors of μ _oxamido Copper(Ⅱ) Binuclear Complex (deCu) in PBS were studied.Cyclic voltammograms of this complex in PBS(pH=9)exhibited two reductive peaks( E pc1 =-0.25 V, E pc2 =-0.50 V)at hanging mercury drop electrode(HMDE),peaks at -0.50 V and -0.25 V corresponded to the reduction of ligand and copper(Ⅱ)_complex, respectively.The spectroelectrochimical experiments showed that there was a new absorption band at 440 nm,and the absorption peaks at 270 nm,280 nm red shifted to 300 nm,310 nm under potential of -0.75 V.It was meant that the Cu(Ⅱ) turned into low valent copper,simultaneously,a new large coupling system …
