Abstract
Kinetic data for the reaction of [FeII(CN)5(OH2)]3–with [FeII(CN)6]4– and [CoIII(CN)6]3– to give [FeII 2(CN)11]7– and [FeIICoIII(CN)11]6– respectively, and the bridge-cleavage reactions of the binuclear complexes, show that these reactions are predominantly dissociative. The bridge-cleavage reaction of [FeIIICoIII(CN)11]5– is much slower than the corresponding reaction of [FeIICoIII(CN)11]6– and the rate of the former complex is accelerated by the addition of [FeII(CN)5(OH2)]3–.Keywords
