A number of symmetrically 3,5-disubstituted 4-amino-1,2,4-triazoles have been prepared by the reaction of aromatic nitriles with hydrazine dihydrochloride or sulfate with an excess of hydrazine hydrate in ethylene or diethylene glycol under a nitrogen atmosphere. The structures of the new triazoles
