Pericyclic transition-state-like aromaticity in the inorganic ions Se2i4(2+) and S2O4(2-).
We show, by means of quantum chemical calculations, that the inorganic ions Se2I4(2+) and S2O4(2-), whose structures have been long-known and well-characterized, have aromaticity resulting from through-space conjugation, analogous to the aromaticity in the transition states of some pericyclic reactions, such as Cope rearrangements and Diels-Alder reactions.
