Abstract:
The photolysis of aqueous solutions of potassium hexacyanoferrate(III) at 254 and 366 nm forms aqua- or hydroxo-pentacyanoferrate(III) in both acidic and alkaline solutions, with quantum yields between 0.02 and 0.06. Subsequent thermal reactions form the decacyanodiferrate(III) and/or decacyanodiferrate(III,II) species, especially in weakly acidic solutions, and, in alkaline solutions, may precipitate hydrated iron(III) oxides.

AbstractThe reactivity of alcohol dehydrogenase IIG (ADH IIG) from Pseudomonas putida HK5 with new heterocycle-pentacyanoferrate(III) complexes and hexacyanoferrate(III) was determined at pH 7.2. The pentacyanoferrate(III) complexes contained imidazole, pyrazole, pyridine, their derivatives and 2-aminobenzothiazole as the sixth ligand. The largest reactivity of the complexes with ADH IIG was estimated for the complex containing pyridine. An apparent bimolecular constant (k ox) for this complex was 8.7 × 105 M−1s−1. The lowest value of k ox was estimated for the complex with benzotriazole (k ox

Kinetic and spectroscopic studies have been carried out in aqueous solution on the formation (from Fe(CN)5OH23−) and dissociation of pentacyanoferrate(II) complexes containing 1-(4-pyridyl)pyridinium and the neutral, protonated, and N-methylated forms of 4,4′-bipyridine (BPY), 1,2-bis(4-pyridyl)ethane (BPA), and trans-1,2-bis(4-pyridyl)ethylene (BPE). The pH dependences of the formation kinetics have been analyzed in terms of the specific rate and acid dissociation constants for these ligands.

Abstract:
The comparison between thermodynamic pKa values and oxidation potentials of the pentacyanoferrate(II) complexes of a series of azoles shows the existence of two parallel lines: one for pyrazoles and another one for benzazoles. Using the equation corresponding to the second one, the pKa value of 1-methylbenzotriazole (2.49) can be estimated from the E1/2 value of its complex. Keywords: azole basicity, oxidation potentials, pyrazoles, benzotriazoles.

Methimazole (2-mercapto-1-methylimidazole, MMI) and its pentacyanoferrate (II) complex have been characterized by means of UV/Vis, Raman, and NMR spectroscopy. The reaction of MMI with aquapentacyanoferrate (II), [Fe(CN)5(H2O)]3−, in buffered aqueous solutions yielded the [Fe(CN)5(MMI)]3−complex. It was found that only thione tautomer of MMI coordinates to the iron (II). The exceptionally stabile and inert complex was produced.

All the complexes exhibited two line spectra with ⊿ EQ = 0.73-1.92 mms-1 and δ = −0.04−0.49 mms-1 (w.r.t. SNP) and can be divided into two groups with well defined parameters. Partial isomer shift and partial quadrupole splitting values were correlated with bonding characteristics.
