Electronic configuration of five-coordinate high-spin pyrazole-ligated iron(II) porphyrinates

Pyrazole, a neutral nitrogen ligand and an isomer of imidazole, has been used as a fifth ligand to prepare two new species, [Fe(TPP)(Hdmpz)] and [Fe(Tp-OCH3PP)(Hdmpz)] (Hdmpz = 3,5-dimethylpyrazole), the first structurally characterized example

Four-coordinate iron(II) porphyrinates: Electronic configuration change by intermolecular interaction

The syntheses and structures of three four-coordinate iron(II) porphyrinates are reported. The three derivatives are tetraarylporphyrin species, where the aryl is either phenyl, p-methylphenyl, or p-methoxyphenyl. One of these derivatives, that of tetraph

Electronic configuration assignment and the importance of low-lying excited states in high-spin imidazole-ligated iron(II) porphyrinates

The synthesis and characterization of six new high-spin deoxymyoglobin models (imidazole-(tetraarylporphyrinato)iron(II)) are described. These have been intensively studied by temperature-dependent Moessbauer spectroscopy from 295 to 4.2 K. All complexes

Synthesis of 5,10,15,20-tetrakisphenylporphins on a carbon support for the cathodic reduction of oxygen in fuel cells

Several substituted Fe- and Co-containing tetraphenylporphins I were loaded on carbon either by adsorption from acetone or by in situ synthesis on the carbon support. The porphin/carbon combinations were pyrolyzed at 800°C. The electrocatalytic activities in the reduction of dioxygen were investigated in alkaline (KOH) and acid (H2SO4) solutions using porous Teflon-bonded carbon electrodes impregnated with the catalysts. At 700 mV high current densities of 75 mA/cm2 in acid solution and up to 90 mA/cm2 in alkaline solution were obtained.

Ligand, Oxygen, and Carbon Monoxide Affinities of Iron(II) Modified Capped Porphyrins

Ligand, O2, and CO binding constants are presented for iron(II) modified capped porphyrins.Steric effects at the axial position outside the cap were altered by changing a tetraphenyl-type cap to a corresponding tetranaphthalene-type cap.The steric hindrance caused by the peri hydrogens of the naphthalene groups is believed to be responsible for the decrease in ligation in the order n-propylamine > isobutylamine > sec-butylamine > tert-butylamine.Inductive effects in the porphyrin plane were altered by introducing a nitro group.Such an electron-withdrawing group enhances ligation but retards oxygenation.The solvent effect on O2 binding by capped complexes is small, presumably because the environment of the O2 bound inside the cap is not greatly changed by changes in solvent.The CO affinities of iron(II) capped porphyrins and of corresponding iron(II) flat-open porphyrins are similar.In contrast, the O2 affinities of the capped systems are lower than their flat-open counterparts, which means the iron(II) capped porphyrin complexes discriminate against O2 but not CO.This is discussed in terms of distal steric effects on the stable structures of Fe-O-O (bent) and Fe-C-O (linear).
