Crystal structure of bis(1-methyl-1<i>H</i>-imidazole-κ<i>N</i> <sup>3</sup>)(5,10,15,20-tetraphenylporphyrinato-κ<sup>4</sup> <i>N</i>)iron(II) toluene trisolvate
The title complex, [Fe(C<sub>4</sub>H<sub>6</sub>N<sub>2</sub>)<sub>2</sub>(C<sub>44</sub>H<sub>28</sub>N<sub>4</sub>)]·3C<sub>7</sub>H<sub>8</sub>, 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<sub>P</sub> (N<sub>P</sub> is a porphyrin N atom) bond length is 1.994 (3) Å and the axial Fe-N<sub>Im</sub> (N<sub>Im</sub> 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<sub>P</sub> vector is 25.54 (10)°. In the crystal, the only significant inter-molecular inter-actions present are C-H⋯π inter-actions.
