We have reported here the synthesis, structure, and properties of low-spin bis-imidazole-coordinated Fe(III) and Fe(II) complexes of 5,10,15,20-tetrakis-(pentafluorophenyl)-2,3,7,8,12,13,17,18-octachloroporphyrin, [Fe-III(TFPPCl8)(L)(2)]ClO4 and Fe-II(TFPPCl8)(L)(2) (L = 1-methylimidazole, 4-methylimidazole, imidazole). The X-ray structure of Fe-II(TFPPCl8)(1-MeIm)(2) is reported here, which demonstrated the near-perpendicular axial ligand orientation (dihedral angle between two 1-methylimidazoles is 80.7 degrees) for Fe(II) porphyrins in a highly saddle-distorted macrocyclic environment. Oxidation of Fe-II(TFPPCl8)(L)(2) using thianthrenium perchlorate produces [Fe-III(TFPPCl8)(L)(2)]ClO4, which was also isolated in the solid state and characterized spectroscopically. The complex gives rhombic EPR spectra in both solid and solution phases at 77 K and thus represents a rare example of nearly parallel axial ligand orientations for the unhindered imidazoles in a saddle-distorted porphyrin macrocycle. Geometry optimization using DFT also converged to the parallel axial alignment when 1-methylimidazole was used as the axial ligand (the dihedral angle between two axial ligands is 8.6 degrees). The potential energy surface (PES) scan results also show that the relatively parallel axial orientations are energetically preferred for Fe(III), while perpendicular orientations are preferred for the Fe(II) complexes reported here. Bulk oxidation of Fe-II(TFPPCl8)(L)(2) in dichloromethane at a constant potential under nitrogen converts it to [Fe-III(TFPPCl8)(L)(2)]ClO4, which gives identical EPR spectra at 77 K and which upon reduction regenerates Fe-II(TFPPCl8)(L)(2) again. Thus, we have demonstrated here very rare examples of Fe porphyrins in which the relative axial imidazole orientations switch between parallel and perpendicular just upon changing the oxidation states of iron from +3 to +2, respectively, in a nonplanar porphyrinic environment. These observations could be immensely important for understanding the possible effects of axial histidine orientations on similar macrocyclic deformations observed in various heme proteins.
