Crystal structure of bis(benzylamine-κN)[5,10,15,20-tetrakis(4-chlorophenyl)porphyrinato-κ4N]iron(II)n-hexane monosolvate

Abstract

In the title compound, [FeII(C44H24Cl4N4)(C6H5CH2NH2)2]·C6H14or [FeII(TPP-Cl)(BzNH2)2]·n-hexane [where TPP-Cl and BzNH2are 5,10,15,20-tetrakis(4-chlorophenyl)porphyrinate and benzylamine ligands, respectively], the FeIIcation 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-symmetricn-hexane solvent molecule per complex molecule. The average Fe—Npyrrolebond length [1.994 (3) Å] indicates a low-spin complex. The crystal packing is sustained by N—H...Cl and C—H...Cl hydrogen-bonding interactions and by C—H...π intermolecular interactions, leading to a three-dimensional network structure.
