Area of Science:

• Coordination Chemistry
• Supramolecular Chemistry
• Materials Science

Background:

• N-confused porphyrins are versatile macrocyclic ligands with unique electronic and structural properties.
• Dimeric metal complexes offer opportunities for studying cooperative effects and developing advanced materials.
• Iron(III) complexes are relevant in catalysis, magnetism, and biomedical applications.

Purpose of the Study:

• To synthesize and characterize a novel dimeric iron(III) complex incorporating an N-confused porphyrin ligand.
• To investigate the solid-state structure and packing of the resulting complex.
• To determine the intramolecular iron-to-iron distance and compare it with existing N-confused porphyrin dimers.

Main Methods:

• Synthesis of the dimeric iron(III) complex via reaction of sodium phenolate and Fe(HCTPPH)Br.
• Single-crystal X-ray diffraction analysis to elucidate the solid-state structure and packing.
• Spectroscopic and analytical techniques for characterization.

Main Results:

• Successful assembly of a dimeric iron(III) complex with a unique channel-like solid-state packing.
• Determination of an intramolecular iron-to-iron distance of 8.864 Å.
• This distance represents the longest reported for dimeric N-confused porphyrin complexes.

Conclusions:

• The study demonstrates the successful synthesis of a novel iron(III) N-confused porphyrin dimer.
• The observed channel-like packing and extended Fe-Fe distance highlight the structural diversity achievable with these systems.
• This complex may serve as a platform for exploring new magnetic or catalytic properties.
