Crystal structure of bis(4-methoxypyridine-κN)(meso-5,10,15,20-tetraphenylporphyrinato-κ4N,N′,N′′,N′′′)iron(III) perchlorate

Abstract

In the crystal structure of the title compound, [Fe(C44H28N4)(C6H7NO)2]ClO4, the FeIII ions are coordinated in an octahedral fashion by four N atoms of the porphyrin moiety and two N atoms of two 4-methoxypyridine ligands into discrete complexes that are located on inversion centers. Charge-balance is achieved by perchlorate anions that are disordered around twofold rotation axes. In the crystal structure, the discrete cationic complexes and the perchlorate anions are arranged into layers with weak C—H...O interactions between the cations and the anions. The porphyrin moieties of neighboring layers show a herringbone-like arrangement.
