“…In papers [4][5][6][7][8] divergences in estimation of stability constants of identical complexes are so evident that they cannot be attributed to different experimental conditions. Electronic and electron paramagnetic resonance (EPR) spectra parameters of the mentioned individual forms were not reported.…”

“…The literature data [4][5][6][7][8] on thermodynamics of complex formation between copper(II) and GSSG are [8] were considered as significant forms. In papers [4][5][6][7][8] divergences in estimation of stability constants of identical complexes are so evident that they cannot be attributed to different experimental conditions.…”

“…Steric interaction between GSSG molecules has previously been inferred from calculations based on potentiometric data (Micheloni et al 1978), but so far no experimental evidence allows the distinction between the two dimer models in Scheme 1. To account for simulations of potentiometric titrations, the existence of an intermediate GSSG dimer with only one Cu2+ bound has been postulated (Micheloni et al 1978, Abello et al 1980, but this result was later ascribed to a computer program artifact (Blais & Berthon 1982).…”

“…Our usual optimization/simulation two stage approach [13,43] was used. For each system, the stoicheiometries of the possible complexes likely to account for the experimental data were derived from the shape of the relevant formation curves.…”
