Metal complexes of N-p-nitrobenzoylamido-meso-tetraphenylporphyrin: cis-acetato-N-p-nitrobenzoylimido-meso-tetraphenylporphyrinatothallium(III) and N-p-nitrobenzoylimido-meso-tetraphenylporphyrinatonickel(II)

This work for the first time reports X-ray crystals of two metal complexes, i.e., a four-coordinate, bridged nickel(II) porphyrin complex, Ni(N-p-NCOC₆H₄NO₂-tpp) (1) with a Ni^II-N-(p-COC₆H₄NO₂)-N (or Ni^II-NNB-N) linkage, and a cisoid six-coordinate, bridged thallium (III) porphyrin complex, Tl(N-p-NCOC₆H₄NO₂-tpp)(OAc) (3) with an Tl^III-N-(p-COC₆H₄NO₂)-N (or Tl^III-NNB-N) linkage. Compound 1 is a distorted square planar, whereas compound 3 is a distorted square-based pyramid in which the apical site is occupied by a chelating bidentate OAc^- group.
