Are Oxocarbon Dianions Aromatic?

Assessment of the cyclic electron delocalization of the oxocarbon dianions, C n O n 2- and their neutral counterparts C n O n (n = 3−6), by means of structural, energetic, and magnetic criteria, shows that C3O3 2- is doubly aromatic (both σ and π cyclic electron delocalization), C4O4 2- is moderatel...
