7-Azidofurazano[3, 4-b]tetrazolo[1, 2-d]pyrazine(AzFTP) and 7-aminofurazano[3, 4-b]tetrazolo[1, 2-d]pyrazine (AmFTP) were synthesized using 5, 6-dichlorofurazano[3, 4-b]pyrazine as starting material, via azidation and amination reaction. The single crystal of AmFTP was firstly cultivated and tested by single-crystal X-ray diffraction. The crystal belongs to orthorhombic system, space group P2₁2₁2₁ with crystal parameters a=0.7117(18) nm, b=0.8088(2) nm, c=1.1871(8) nm, V=0.6833(3) nm³, Z=4, D_c=1.732 g·cm^-3, μ=0.138 mm^-1, F(000)=360, R₁=0.0376, wR₂=0.0988. Thermal properties of target compounds were studied using differential scanning calorimetry(DSC) and thermogravimetric(TG). Results show that AmFTP has better thermal stability than AzFTP.
