Abstract

Calculation of high σ-delocalisation in the iodine periphery of the hexaiodobenzene cation, accompanied by a four-electron through-space σ ring current, provides direct computational evidence for the attribution to this ion of σ-aromaticity co-existing with the conventional π-aromaticity that it shares with its neutral parent.
