One-electron oxidation of 1,4-dithiin annelated with bicyclo[2.2.2]octene units (3) by SbF5 afforded stable radical cation salt 3'+SbF6 -. The X-ray crystallography indicated that the dithiin ring of 3 '+ is planar in agreement with the theoretical prediction. The ESR coupling constant (as) due to 3
