Some new 1,2,3‐triazolo[4,5‐ d ]‐1,2,4‐triazolo[4,3‐b]pyridazines were prepared starting from the corresponding 1,2,3‐triazolo[4,5‐ d ]pyridazines via the formation of the 1,2,4‐triazole ring, by condensation of an appropriate monocarbon fragment with the 4‐hydrazino substituent and the nitrogen atom in the 5 position of the heterocycle. Condensation of 4‐phenylhydrazino substituted derivatives with formic acid gave zwitterionic compounds.
