• 論文の詳細を見る

• An oxo-bridged, mixed-valence complex of ruthenium(IV,III), [(edta)Ru<SUP>IV</SUP>ORu<SUP>III</SUP>(edta)<SUP>3−</SUP>, has been obtained from the oxidation of [Ru<SUP>III</SUP>(edta)(H<SUB>2</SUB>O)]<SUP>−</SUP> by chlorate ions. The formulation of the complex as a μ-oxo dimer of ruthenium(IV,III) is based on the results of a variety of experiments, including elemental analyses, magnetism, by spectrophotometry, and by electrochemical studies. These studies in acetate buffer solution show that the dimeric ion can be reduced at mercury electrode to [(edta)Ru<SUP>III</SUP>ORu<SUP>III</SUP>(edta)]<SUP>4−</SUP> and then is monomerized to the original [Ru(edta)(H<SUB>2</SUB>O)]<SUP>−</SUP> in a fast reaction.
