Nitrato(2,3,7,8,12,13,17,18-octaethylporphyrinato)iron(III)

Abstract

The crystal structure of [Fe(C36H44N4)(NO3)] has been determined in the space group P1. The unit cell contains two molecules. The Fe atom is displaced out of the porphyrin plane by 0.50 A, the average Fe-Np distance is 2.056 (1) A (where Np is a porphyrin N atom) and the Fe-O(NO3) bond length is 2.016 (3) A.

Structural and physical characterization of (nitrato)iron(III) porphyrinates [Fe(por)(NO3)] – Variable coordination of nitrate

“…The first of these, monoclinic [Fe(OEP)(NO 3 )], represents a second crystalline example of a monodentate nitrate coordinated system in an iron(III) porphyrinate. 15 The second structure, [Fe(TPP)(NO 3 )], is a redetermination of a previously reported room temperature structure. 16 Here, we report a revised structure from data collected at 100 K. for the major and minor orientations respectively.…”

FTIR and optical spectroscopic studies of the reactions of heme models with nitric oxide and other NOx in porous layered solids

“…The energy difference between bidentate and monodentate coordination must be small given that the octaethylporphyrinato analog Fe III (OEP)( 1 -ONO 2 ) is monodentate [72], and this view is supported by DFT computations with the porphinato complex Fe(P)(NO 3 ). While one might expect the heme complexes to be susceptible to binding a ligand in the axial site trans to the nitrato ligand, examples of such six-coordinate complexes were limited to the aqua complex Fe(P)(H 2 O)( 1 -ONO 2 ) (P not identified) described in a review by Wyllie and Scheidt [28].…”

Explorations in metalloporphyrin stereochemistry, physical properties and beyond

“…Further, I would take notice of two bodies of work that have not been discussed in this paper, work on the other oxynitrogen-ligated porphyrins (the ligands NO 2 − and NO 3 − ) [112][113][114][115][116][117][118][119][120][121][122][123][124] and the work on the characterization of π-cation radical complexes [125][126][127][128][129][130][131][132][133][134][135][136][137][138][139].
