摘要：

gamma-irradiation and pulse radiolysis are used to check experimentally the ligand effect of the redox potential of the cyano-silver monomer couple Ag-1(CN)(2)(-)/Ag-0(CN)(2)(2-) found to be lower than -2.1 V-NHE instead of equal to -2.6 V-NHE as in a previous theoretical evaluation (Remita et al., 1995, Journal of Physical Chemistry 99, 13198). We present a mechanism explaining the reduction of Ag(CN)(2)(-) by the radical anion (CH3)(2)CO- indicating that the redox potential of the couple [2Ag(1)(CN)(2)(-)/Ag-2(+), xCN(-)] lies between -2.1 and -1.7 V-NHE Copyright (C) 1997 Elsevier Science Ltd.
