Quinonoid mesoioniccompounds having a 2,3-diphenyltetrazolium ring were synthesized and characterized spectroscopically. Compounds possessing an inserted benzene ring were found that a dipolar (5-tetrazolylio)phenolate structure contributes importantly to the ground state of the mesoions. On the contrary, a mesoion having an inserted anthracene ring is a less polar compound, anthraquinone methide
