Furoxan has been extensively studied due to its high energy provided by potential “nitro” fragment， but the relatively poor stability limits its practical applications. A novel energetic compound， 3，3''-（1，2，5-oxadiazole-3，4-diyl）bis（1，2，4-oxadiazol-5-amine）（1）， was synthesized from dicyanofuroxan via a three-step procedure involving reduction， oximation， and cyclization-dehydration reactions. Subsequent nitration of 1 afforded 3-（4-（5-amino-1，2，4-oxadiazol-3-yl）-1，2，5-oxadiazol-3-yl）-1，2，4-oxadiazol-5（4H）-one（2）. The structures of both compounds were characterized by nuclear magnetic resonance （NMR） spectroscopy， elemental analysis （EA）， infrared （IR） spectroscopy， and single crystal X-ray diffraction analyses. Results show that compound 1 crystallizes in orthorhombic crystal system， space group Pbcn， Z = 4， with a crystal density of 1.825 g·cm⁻³. The trihydrate of compound 2·3H₂O crystallizes in triclinic crystal system， space group P1， Z = 2， with a crystal density of 1.641 g·cm^-3 Both compounds exhibit high insensitivity to mechanical stimuli， with impact sensitivity >40 J and friction sensitivity >360 N. Their calculated detonation velocity （7921 m·s^-1 for 1 and 7660 m·s^-1 for 2） and detonation pressure （22.4 GPa for 1 and 20.5 GPa for 2） are superior to those of TNT （6881 m·s^-1， 19.5 GPa）.
