Abstract
Two energetic compounds based on 5-methyl-1-aminotetrazole were prepared. The trinitroethyl moiety and furazan ring were introduced to tetrazole, respectively. The trinitroethyl moiety can increase the oxygen balance, and the furazan ring can improve the detonation properties. The structures of both compounds were confirmed by X-ray crystallography. Their thermal stability and explosive performance were also investigated.

h Oxygen balance (OB) is an index of the deficiency or excess of oxygen in a compound required to convert all C into CO2 and all H into H2O, for the compound with the molecular formula of CaHbNcOd (without crystal water), OB (%) = 1600[(d − 2a − b/2)/Mw] (%).
i Electrostatic discharge.
