Aqueous solutions of Fe(OH2)62+ interact producing an intensely blue colored ion of the formula [(OH2)5FeOOs(en)2O]4+ which has been isolated in the solid state as the sulfate salt. Oxidation-reduction is not involved and the formation and dissociation are rapid. Equilibrium quotients have been evaluated and it is shown that K2 ⪢ K1.
