    • Abstract

       

      Spectral, cyclic voltammetric (CV) and differential pulse voltammetric (DPV) studies on some bis’s(alicyclic-α-amino acidato)copper(II) complexes, CuL2, whereL is alicyclic α-amino acid, at various pH values have been carried out in aqueous media. Electronic absorption and ESR spectral studies at lower pH levels indicate formation of protonated species. At neutral pH these complexes undergo a reversible one-electron Cu(II)⇌Cu(I) redox process at about −0.24 V vs saturated calomel electrode (SCE), at the hanging mercury drop electrode. The electrochemical behaviour of the complexes at lower pH values is discussed in terms of the different species present
