Porphyrins Phthalocyanines"],"published-print":{"date-parts":[[2016,1]]},"abstract":"<jats:p> The reaction of [Fe(TMP)(OClO[Formula: see text]], where TMP is the dianion of tetramesitylporphyrin, with a combination of a strong [Formula: see text]-acceptor ligand and a [Formula: see text]-donating imidazole can lead to the preparation of mixed-ligand complexes [Fe(Porph)(4-CNPy)(L)][Formula: see text] where L is imidazole itself or 1-acetylimidazole and 4-cyanopyridine is the strong [Formula: see text] acceptor ligand. The stability of the new mixed-ligand pair is the presumed result of synergic bonding between the two axial ligands. The molecular structure and other characterization of the new mixed axial ligand complex, [Fe(TMP)(4-CNPy)(HIm)]ClO<jats:sub>4<\/jats:sub> is described. The axial ligands have a relative perpendicular arrangement with Fe\u2013N(imidazole) = 1.945 \u00c5 and Fe\u2013N(pyridine) = 2.021 \u00c5. The average equatorial Fe\u2013N[Formula: see text] distance is 1.963 \u00c5, which is consistent with the S<jats:sub>4<\/jats:sub>-ruffled TMP core. Despite the relative perpendicular arrangement of axial ligands, the EPR spectrum of the complex is a rhombic signal and not a large g<jats:sub>max<\/jats:sub> signal. The EPR g-values are [Formula: see text] 3.05, [Formula: see text] 2.07, and [Formula: see text] 1.22. A quadrupole doublet was seen in the M\u00f6ssbauer spectrum with an isomer shift of 0.197 mm\/s and quadrupole splitting of 1.935 mm\/s. Two crystalline forms of [Fe(TMP)(4-CNPy)(HIm)]ClO<jats:sub>4<\/jats:sub> have been characterized; the two forms differ only in the solvent content of the lattice.
