Bis(1,4-diamino-1,2,4-triazolium) sulfate (1) was obtained from the corresponding chloride by ion metathesis using Ag2SO4. Further metathesis with barium 5,5′-azotetrazolate yielded bis(1,4-diamino-1,2,4-triazolium) 5,5′-azotetrazolate (2). Numerous NH···N and NH···O interactions were identified in the crystal structures of 1 and 2. Both compounds undergo exothermal decomposition upon heating. View Full-Text
