Tetrakis(alkoxycarbonyl)porphyrin and its β-octafluoro-substituted derivatives were synthesized via Lindsey method and transformed to their zinc complexes. Single crystal X-ray structures of corresponding Zn(II) porphyrins revealed that β-octafluorination will give more compactness of porphyrin moieties in the crystal structure owing to the hydrogen bonding interactions involving β-fluorine atoms. An unusual six-coordinated Zn(II) was found via intramolecular coordination of oxygen atom of meso-substituents with central Zn(II).
