Abstract

The interaction of Ru(III) with IMDA, HEDTA, EDTA, PDTA, CDTA and DTPA was studied by potentiometric and spectrophotometric methods at 25°C and 0.10 M ionic strength. Experiments were carried out under nitrogen and oxygen atmospheres. Evidence for the formation of dioxygen complexes in these systems is presented. Stability constants for the different species existing in each of the systems were calculated using a computer programme. Ru(III) forms very strong complexes with aminopolycarboxylic acids, which then interact with molecular oxygen to form a series of μ-peroxo and μ-hydroxo-μ-peroxo complexes.
