Crystal structure of bis(benzylamine-kappa N)[5,10,15,20-tetrakis(4-chlorophenyl)porphyrinato-kappa N-4]iron(II) n-hexane monosolvate

In the title compound, [Fe-II(C44H24Cl4N4)(C6H5CH2NH2)(2)]center dot C6H14 or [Fe-II(TPP-Cl)(BzNH(2))(2)]center dot n-hexane [where TPP-Cl and BzNH(2) are 5,10,15,20-tetrakis(4-chlorophenyl)porphyrinate and benzylamine ligands, respectively], the Fe-II cation lies on an inversion centre and is octahedrally coordinated by the four pyrrole N atoms of the porphyrin ligand in the equatorial plane and by two amine N atoms of the benzylamine ligand in the axial sites. The crystal structure also contains one inversion-symmetric n-hexane solvent molecule per complex molecule. The average Fe-N-pyrrole bond length [1.994 (3) angstrom] indicates a low-spin complex. The crystal packing is sustained by N-H center dot center dot center dot Cl and C-H center dot center dot center dot Cl hydrogen-bonding interactions and by C-H center dot center dot center dot pi intermolecular interactions, leading to a three-dimensional network structure.
