EN The formation of iron(III) complexeswith chelating bromokojate anions L– was investigated in aqueous solutions as a function of the pH and c(Fe3+) : c(HL) molar ratio. Stability constants of the complexes [FeL(H2O)4]2+, [FeL(H2 O)3(OH)]+, [FeL2 (H2O)2]+, [FeL2(H2O)(OH)] and [FeL2(OH)2]– were determined by the evaluation of UV-VIS spectral data. Based on the stability constants, distribution of the above complexes, [Fe(H2O)6]3+, and [Fe(H2O)5(OH)]2+ in solutions of various composition were calculated. The paper indicates a compatibility of the used data treatment and that not taking hydroxo complexes into account. Properties of the investigated bromokojic acid and its iron(III) complexes are compared to those required for therapeutic application as alternative iron chelators.
