The bond lengths of the 4-dimethylaminopyridinium moiety suggest a semiquinoid resonance form with a dou­ ble bond to the exocyclic nitrogen and two local­ ized carbon-carbon double bonds in the ring. The ring and the exocyclic N and S atoms of the cation are essentially coplanar. The S -N bond distances in the cation (173.4 pm) and the anion (159.1 and 159.6 pm) correlate with Pauling bond orders of 1.0 and 1.7, respectively. The anion displays a staggered conformation with approximate C2 symmetry (S -N -S 120.4°).
