Crystal structure of bis-(1-methyl-1H-imidazole-κN (3))(5,10,15,20-tetra-phenyl-porphyrinato-κ(4) N)iron(II) toluene tris-olvate.

The title complex, [Fe(C(4)H(6)N(2))(2)(C(44)H(28)N(4))]·3C(7)H(8), possesses inversion symmetry with the iron(II) atom located on a center of symmetry. The metal atom is coordinated in a symmetric octa-hedral geometry by four pyrrole N atoms of the porphyrin ligand in the equatorial plane and two N atoms of 1-methyl-imidazole ligands in the axial sites; the complex crystallizes with three toluene solvent mol-ecules. The average Fe-N(P) (N(P) is a porphyrin N atom) bond length is 1.994†(3)†à and the axial Fe-N(Im) (N(Im) is an imidazole N atom) bond length is 2.0000†(14)†à . The two 1-methyl-imidazole ligands are mutually parallel. The dihedral angle between the 1-methyl-imidazole plane and the plane of the closest Fe-N(P) vector is 25.54†(10)°. In the crystal, the only significant inter-molecular inter-actions present are C-H⋯π inter-actions.
