Crystal structure of bis-(1-methyl-1H-imidazole-κN (3))(5,10,15,20-tetra-phenyl-porphyrinato-κ(4) N)iron(II)-1-methyl-1H-imidazole (1/2).

ABSTRACT: The title compound, [Fe(C44H28N4)(C4H6N2)2]·2C4H6N2, is a six-coordinate Fe(II)-porphyrinate complex with the metal located on a center of inversion and coordinated by two axial 1-methyl-imidazole ligands; the complex crystallizes as a 1-methyl-imidazole disolvate. The 1-methyl-imidazole group bonded to the Fe(II) atom [occupancy ratio 0.789 (4):0.211 (4)] and the unbound 1-methyl-imidazole mol-ecule [0.519 (4):0.481 (4)] were disordered. The average Fe-N(porphyrinate) bond length is 1.998 (3) Å and the axial Fe-N(imidazole) bond length is 1.9970 (12) Å. In the crystal, mol-ecules are linked into a three-mol-ecule aggregate by two weak C-H⋯N inter-actions.
