Preparation and characterization of mono-imidazole ligated (meso-tetramesitylporphyrinato)iron(III) complexes: Model for cytochromes c'
A series of mono-imidazole ligated (meso-tetramesityl-porphyrinato)iron(III) complexes have been prepared. The spin states of these complexes are presented as the admired intermediate (S = 3/2, 5/2) on the basis of the H-1 NMR, C-13 NMR, EPR, and magnetic moments. The S = 3/2 character has increased as the axial imidazole ligand becomes bulkier.
