A NOVEL PORPHYRIN ISOMER - HEMIPORPHYCENE - FORMATION AND SINGLE-CRYSTAL X-RAY-DIFFRACTION STRUCTURE DETERMINATION OF A HEMIPORPHYCENE NICKEL-COMPLEX

Hemiporphycene ([18]porphyrin-(2,1,1,0)), an additional isomer of the porphyrin ring system, has been obtained by ring contraction of a homoporphyrin. Two isomeric triphenylcarboethoxyhemiporphycene nickel complexes and a corresponding free base have been characterized and the X-ray structure analys...

Summary:Hemiporphycene ([18]porphyrin-(2,1,1,0)), an additional isomer of the porphyrin ring system, has been obtained by ring contraction of a homoporphyrin. Two isomeric triphenylcarboethoxyhemiporphycene nickel complexes and a corresponding free base have been characterized and the X-ray structure analysis of one of the nickel complexes carried out.
