Abstract A new heteropoly complex PW11RuIV and complexes of RuII, RuIII and RuV based thereon have been obtained. Using specrophotometry the states of RuIII and RuIV complexes in solution, the pH range of their stability, and the interaction of PW11RuIV with ClO4 −,SO4 2−, Cl− ions have been studied. A conclusion has been thus made that the ruthenium ion in such a complex is not incorporated in the heteropolyanion lattice, but is attached only to its external oxygen atoms. Kinetics of oxidation of PW11RuIV and PW11RuIII with potassium chlorate have been studied. The activation energy and pre-exponential factor have been found for the reaction. The possibility that ClO4 − and ClO3 − in aqueous solutions can be activated by PW11RuII with the former and by PW11RuIII and PW11RuIV with the latter has been demonstrated.
