Substitution reactions of the ions [FeIII(CN)5X]2–(X = NH3 and H2O) by Y {Y = N3–, SCN–, OH–, and [Co(CN)6]3–} are catalysed by [FeII(CN)5X]3–. At iron(II) concentrations greater than ca. 1% of the total iron species present, the rate-determining step of these reactions is substitution of the ions [FeII(CN)5X]3– by Y.
