A trifluoromethyl-containing fused triazole-triazine energetic molecule， 3-（1H-tetrazol-5-yl）-7-（trifluoromethyl）-1，2，4-triazolo［5，1-c］-1，2，4-triazin-4-amine （2）， was synthesized in two steps from 5-（trifluoromethyl）-1，2，4-triazol-3-amine. The crystal structure of this compound was characterized by X-ray single crystal diffraction. Its structure and properties were characterized by ¹H and ¹³C Nuclear Magnetic Resonance Spectroscopy （NMR）， Fourier Transform infrared spectroscopy （FT-IR） and differential scanning calorimetry （DSC）. The detonation performance of compound 2 was predicted by EXPLO5 and and sensitivity testing was performed according to the BAM standard method. Results show that compound 2 belongs to the triclinic space group Pī， a=4.9035（10） Å， b=10.219（2） Å， c=15.194（3） Å， V=720.4（3） ų， α=107.163（6）°，β=92.486（7）°，γ=96.4438（7）°， Z=2. The theoretical detonation velocity and pressure of compound 2 are 6933 m·s^-1 and 17.1 GPa， respectively. Its measured impact sensitivity is more than 40 J and the friction sensitivity is larger than 360 N.
