摘　　要：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）.Tetrakis（alkoxycarbonyl）porphyrin and its β-octafluoro-substituted derivatives were synthesized via Lindsey method and transformed to their zinc complexes.
