Nickel(II), palladium(II), and platinum(II) complexes of meso-arylsubstituted hexaphyrin have been prepared and structurally characterized. In mono-metalated complexes, the metal ion is commonly bound with three pyrrolic nitrogen atoms and one pyrrolic β-carbon, whereas a bis-Pd(II) complex exhibits a unique structure involving a Pd-C α bond. These results reveal novel coordination abilities of the hexaphyrin that lead to a metal-carbon bond at either pyrrolic C β or Cα position.
