Crystal structure of bis­(1-methyl-1H-imidazole-κN3)(5,10,15,20-tetra­phenyl­porphyrinato-κ4N)iron(II) toluene tris­olvate

Abstract

The title complex, [Fe(C₄H₆N₂)₂(C₄₄H₂₈N₄)]·3C₇H₈, possesses inversion symmetry with the iron(II) atom located on a center of symmetry. The metal atom is coordinated in a symmetric octa­hedral geometry by four pyrrole N atoms of the porphyrin ligand in the equatorial plane and two N atoms of 1-methyl­imidazole ligands in the axial sites; the complex crystallizes with three toluene solvent mol­ecules.

The title complex, [Fe(C₄H₆N₂)₂(C₄₄H₂₈N₄)]·3C₇H₈, possesses inversion symmetry with the iron(II) atom located on a center of symmetry. The metal atom is coordinated in a symmetric octa­hedral geometry by four pyrrole N atoms of the porphyrin ligand in the equatorial plane and two N atoms of 1-methyl­imidazole ligands in the axial sites; the complex crystallizes with three toluene solvent mol­ecules. The average Fe—N_P (N_P is a porphyrin N atom) bond length is 1.994 (3) Å and the axial Fe—N_Im (N_Im is an imidazole N atom) bond length is 2.0000 (14) Å. The two 1-methyl­imidazole ligands are mutually parallel. The dihedral angle between the 1-methyl­imidazole plane and the plane of the closest Fe—N_P vector is 25.54 (10)°. In the crystal, the only significant inter­molecular inter­actions present are C—H⋯π inter­actions.
