Ni(III) Complex of an N-Confused Porphyrin Inner C-Oxide

A novel, structurally characterized Ni(III) complex of an N-confused porphyrin inner C-oxide has been synthesized from the oxidation of a Ni(II) N-confused porphyrin using OsO4. Crystal data: C53H40N5NiO.CH2Cl2, monoclinic, space group P2/a (No. 13), a = 21.229(1) A, b = 8.6451(5) A, c = 25.762(2) A, (beta) = 93.004(3)°, V= 4721.6(5) A^3, and Z= 4.
