Crystal structure of bis(2-methyl-1H-imidazole-κN (3))(meso-tetra-p-tolylporphyrinato-κ(4) N)iron(III) perchlorate tetrahydrofuran sesquisolvate
In the title compound, [Fe(C(48)H(36)N(4))(C(4)H(6)N(2))(2)]ClO(4)·1.5C(4)H(8)O, the iron(III) metal is coordinated in a distorted octahedral geometry by four pyrrole N atoms of the porphyrin ligand in the equatorial plane and two N atoms of 2-methylimidazole ligands in the axial sites. The comple...

Sumario: | In the title compound, [Fe(C(48)H(36)N(4))(C(4)H(6)N(2))(2)]ClO(4)·1.5C(4)H(8)O, the iron(III) metal is coordinated in a distorted octahedral geometry by four pyrrole N atoms of the porphyrin ligand in the equatorial plane and two N atoms of 2-methylimidazole ligands in the axial sites. The complex has a highly ruffled porphyrin core with mean absolute core-atom displacements C (a), C (b), C (m) and C (av) of 0.25 (5), 0.17 (12), 0.432 (16) and 0.25 (13) Å, respectively. One of the four phenyl groups of the porphyrin is disordered over two sets of sites with refined occupancy ratio of 0.718 (7):0.282 (7). The mean Fe—N(p) (N(p) is a porphyrin N atom) bond length [1.975 (9) Å] indicates the low-spin state of the iron atom. The two 2-methylimidazole ligands are nearly perpendicular and form a dihedral angle of 86.93 (10)°. The dihedral angles between the 2-methylimidazole ligands and the closest Fe—N(p) vector are 38.04 (9) and 35.00 (7)°. In the crystal, the complex cations interact with the perchlorate anions through N—H⋯O hydrogen bonds, forming chains running parallel to [110]. |
