Abstract

The oxydiacetate complexes of copper(II) with 2,2′-bipyridine (bipy) and 1,10-phenanthroline (phen) have been investigated towards their kinetic and thermodynamic stability. The kinetics of the substitution reactions of the oxydiacetate complex of Cu2+ with bipy and phen have been studied in two types of surfactant solutions - anionic dodecyl sulfate sodium (SDS) and cationic hexadecyl trimethyl-ammonium bromide (CTAB). The values of the observable rate constants for the studied reactions have been determined using the “Glint” program.Moreover, the thermodynamic stability of the copper(II) complexes with oda, phen and bipy in aqueous solutions has been investigated using potentiometric titration method (PT). The concentration distributions of the studied complexes as a function of pH calculated based on the values of log βpqrs have been determined. Additionally, the antioxidant activities of the oxydiacetate complexes of copper(II) with bipy and phen have been studied by the nitro blue tetrazolium (NBT) test and the cyclic voltammetry (CV) technique.
