Abstract
The electrochemical behaviour of silver(I)- and silver(II)-bipyridyl complexes has been investigated using voltammetry, cyclic voltammetry and coulometry in propylene carbonate. In unbuffered non-acidic medium, when the stoichiometry of the solutions is C L/C Ag = 2, the Ag I(bipy) + concentration is low; the preponderant species is Ag I(bipy) 2 +. Under such conditions, the Ag II(bipy) 2 2+/Ag I(bipy) 2 + couple hs a reversible behaviour and is one of the must powerful oxidants used in the solvent ( E ′° = 0.790 V vs E Fc ′° + Fc). As a function of the acidity level of the solutions, one observes the oxidation of either Ag I(bipy) + or Ag + in the presence of the protonated ligand to complexed Ag(II). The silver(II) species produced oxidizes water and the excess of ligand (C L/C Ag > 2).
