Proton-mediated electron configuration change in high-spin iron(II) porphyrinates.

چکیده
The synthesis, molecular structure, and electronic structure characterization of two five-coordinate high-spin imidazolate-ligated iron(II) porphyrinates are reported. Their electronic structure, as deduced from Mössbauer spectra obtained in strong magnetic fields, is distinctly different from that of the analogous imidazole-ligated species. The resulting electronic structure models are consistent with all observed differing features in the two classes.

The title mol-ecule, [Fe(C(36)H(44)N(4))Cl]·1.5CH(2)Cl(2), is a high-spin square-pyramidal iron(III) porphyrinate with an average value for the equatorial Fe-N bond lengths of 2.065 (3) Å and an axial Fe-Cl distance of 2.2430 (13) Å. The iron cation is displaced by 0.518 (1) Å from the 24-atom mean plane of the porphyrin ring. These values are typical for high-spin iron(III) porphyrinates.
متن کاملSolution behavior of iron(III) and iron(II) porphyrins in DMSO and reaction with superoxide. Effect of neighboring positive charge on thermodynamics, kinetics and nature of iron-(su)peroxo product.
The solution behavior of iron(III) and iron(II) complexes of 5(4),10(4),15(4),20(4)-tetra-tert-butyl-5,10,15,20-tetraphenylporphyrin (H(2)tBuTPP) and the reaction with superoxide (KO(2)) in DMSO have been studied in detail. Applying temperature and pressure dependent NMR studies, the thermodynamics of the low-spin/high-spin equilibrium between bis- and mono-DMSO Fe(II) forms have been quantifie...
متن کامل(Cryptand-222)potassium(+) (hydrogensulfido)[5,10,15,20-tetrakis(2-pivalamidophenyl)porphyrinato]ferrate(II)
As part of a systematic investigation for a number of Fe(II) porphyrin complexes used as biomimetic models for cytochrome P450, crystals of the title compound, [K(C(18)H(36)N(2)O(6))][Fe(II)(C(64)H(64)N(8)O(4))(HS)], were prepared. The compound exhibits a non-planar conformation with major ruffling and saddling distortions. The average equatorial iron-pyrrole N atom [Fe-N(p) = 2.102 (2) Å] bond...
متن کاملThe interaction of the Rieske iron-sulfur protein with occupants of the Qo-site of the bc1 complex, probed by electron spin echo envelope modulation.
The bifurcated reaction at the Q(o)-site of the bc(1) complex provides the mechanistic basis of the proton pumping activity through which the complex conserves redox energy in the proton gradient. Structural information about the binding of quinone at the site is lacking, because the site is vacant in crystals of the native complexes. We now report the first structural characterization of the i...
متن کاملConversion of electron configuration of iron ion through core contraction of porphyrin: implications for heme distortion.
It was demonstrated experimentally that nonplanar iron porphyrins can be induced to undergo a conversion in their electronic configuration to form a cross-hybrid transition by compressing the macrocyclic core size for the central metal ion. A series of monostrapped iron porphyrins were used as model systems, and their electronic properties were probed using electron spin resonance and different...
