4H-［1，2，3］Triazolo［4，5-c］［1，2，5］oxadiazole 5-oxide （TODO）hydroxylamine salts and TODO amine salts were synthesized via nitration， cyclization and salt-forming reaction using 3，4-diaminofuran. At the same time， an energetic eutectic（HATODO/ATODO cocrystal） was synthesized by TODO hydroxylamine salts（NH₃OH⁺C₂H₅O^-）and TODO amine salts（NH₄⁺C₂H₅O^-）as raw materials. Its structure was characterized by SXRD，FT-IR and NMR， and the thermal decomposition was studied by TG-DSC. The mechanical sensitivities were tested according to the GJB772A-97 method and the detonation performance was calculated. Results show that the structure of the HATODO/ATODO cocrystal belongs to the monoclinic crystal system， the P2₁/c space group， a=8.5202（3） Å， b=10.3870（4） Å，c=13.4481（4）Å， α=90°， β=102.0510（10）， γ=90°， V=1163.92（7） ų， Z=4.TODO hydroxylamine salts initial decomposition temperature is about 147.9 ℃， TODO amine salts initial decomposition temperature was about 181.3 ℃， whereas the initial decomposition temperature of energetic HATODO/ATODO cocrystal is about 151.2 ℃. The sensitivities of HATODO/ATODO cocrystal is comparable to ADN. The calculated detonation velocity and pressure of HATODO/ATODO cocrystal is 8462 m·s^-1 and 32.07 GPa.
