Norcorrole: Aromaticity and Antiaromaticity in Contest

shielding studies demonstrate that nickel norcorrole (NiNc) and norcorrole
(H2Nc) provide unusual examples of stable molecules with
high antagonistic levels of antiaromaticity and aromaticity: Both
incorporate an antiaromatic “core”, a 14-membered cyclic
conjugated subsystem with 16 π electrons, surrounded by an aromatic
“halo” in the form of a ring of either 14 atoms and
14 π electrons with a new type of homoconjugation (NiNc), or
18 atoms with 18 π electrons (H2Nc).
