Summary

The stability constant for [FeII(CN)5(4-picam)]3− (4-picam=4-picolylamine), K2, was calculated from the measured dissociation and formation constants. The reduction potential obtained by cyclic voltammetry allowed the calculation of K3. Comparison of K2 and K3 for this and other substituted pentacyanoferrate(II) complexes supports the fact that bonding properties of azines coordinated to {Fe(CN)5}n− change with the iron oxidation state. The variation on the rate of release of 4-picam with pH and added electrolyte concentration was interpreted on the basis of solvent effects.
