Abstract

The stability constants of the dioxygen complexes of Ru(III) with amino po,],ycarboxylic acids, HEDTA, EDTA, DTPA and TTHA have been determined in aqueous solution. The polarographic and cyclic voltametric behavior of the Ru(III) dioxygen complexes have been investigated and the complexes characterized by their electronic absorption spectra. The rate of formation of these complexes at one atmosphere of molecular oxygen are reported. Novel paramagnetic superoxo complexes of Ru(III) of the composition K[Ru(L)(O )] (L = EDTAH, HEDTA) are also reported.
