Salts of the tetraazapentalenediylium ions 1 are readily accessible by reaction of the 3,5‐bis(dialkylamino)‐1,2,4‐triazoles with 1,3‐dichloro‐2‐azavinaamidinium salts. According to theoretical predictions they are best described as largely delocalized, almost planar 8π‐electron systems. Reduction with zinc afforded the 1,3,5,7‐tetrazocines 2 , whose structure corresponds to that of octamethylcyclooctatetraene.
