During our studies towards the preparation of the pentagonal‐pyramidal hexamethylbenzene dication C 6 (CH 3 ) 6 2+ , we isolated the unprecedented dicationic species C 6 (CH 3 ) 6 SO 2+ (AsF 6 − ) 2 from the reaction of hexamethylbenzene with a mixture of anhydrous HF, AsF 5 , and liquid SO 2 . This compound can be understood as a complex of unknown SO 2+ with hexamethylbenzene. Herein, we report on its synthesis, molecular structure, and spectroscopic characterization.
