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

The title complex, [Fe(CHN)(CHN)]·3CH, 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 (N is a porphyrin N atom) bond length is 1.994 (3) Å and the axial Fe-N (N is an imidazole N atom) bond length is 2.0000 (14) Å. 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 vector is 25.54 (10)°. In the crystal, the only significant inter-molecular inter-actions present are C-H⋯π inter-actions.
