Chemdraw depictions of iron(II) complexes of 2,4-diacetyldeuteroporphyrin IX dimethyl ester (A), protoporphyrin IX (B), octaethylporphyrin (C), and tetraphenylporphyrin (D) with substituted imidazole axial ligands; tetramesitylporphyrin (E) with axially ligated piperidine; examples of systems with tethered axial bases [F (PIm) and G (PPy)]; “picket-fence” porphyrin with substituted imidazole axial ligands (H); single-strapped (I), and double-strapped (J) “basket-handle” porphyrins; examples with steric bulk at both sides of the porphyrinate (K, M); and examples of capped porphyrinates (L, M). See the text for further discussions of these complexes.
