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) degrees, V=4721.6(5) A3, and Z=4.
