Three new high-nitrogen energetic compounds bis-(ammonium)-5,5′-Azotetrazolate, bis-(guan-idinium)-5,5′-Azotetrazolate and bis-(triaminoguani-dinium)-5,5′-Azotetrazolate have been synthesized from 5-aminotetrazole as a starting materials. Their structures were identified by IR, NMR, DSC, melting point test and elemental analysis. Their explosive performances were also introduced. It shows that these azotetrazolate compounds are possessed of positive enthalpy of formation, high gas generating ability with little or no smoke or residue produced, nonhygroscopic and excellent explosive performances. They are the important ingredients of gas generants, low signature propellants, pyrotechnics and high performance explosives.
