Procedure

1,2-Benzenedicarboxylic acid, 1.66 g (0.01 mole) was added in one portion to a solution of 1.8 g (0.01 mole) of 4,4'-azodipyridine in 25 ml acetone. The reaction mixture was stirred at room temperature for one hour. The resultant suspension was filtered to leave an orange solid. Recrystallization from ethanol yielded 2.1 g of 4,4'-azodipyridinium-1,2-benzenedicarboxylate, having a m.p. of 171°-173° C.
