Abstract

The reaction of [Co^III(TPP)Cl] (TPP is the dianion of 5,10,15,20-tetraphenylporphyrin) with an excess of 4-nitroaniline in dichloromethane leads to the title compound, [Co^III(C₄₄H₂₈N₄)(C₆H₆N₂O₂)₂]Cl·CH₂Cl₂. The Co^III ion lies on an inversion centre and is octahedrally coordinated by two N atoms of the NH₂ groups of the two 4-nitroaniline trans-axial ligands and four pyrrole N atoms of the porphyrin. The asymmetric unit contains one half of the [Co^III(TPP)(4-nitroaniline)₂]⁺ ion complex, one chloride counter-ion (lying on a twofold rotation axis) and one half dichloromethane solvent molecule, where the C atom lies on a twofold rotation axis. The average equatorial Co—N(pyrrole) distance (Co—Np) is 1.982 (2) Å and the axial Co—N(4-nitroaniline) bond length is 2.006 (2) Å. The crystal packing is stabilized by an N—H⋯Cl hydrogen bond between the N atom of the amino group of the 4-nitroaniline axial ligand and the chloride counter-ion. The supramolecular architecture is further stabilized by weak C—H⋯π interactions.
