3,4-Bis(4 -azidofurazano-3 -yl)furoxan (DAZTF), a novel energetic material, was devised for the first time and synthesized from 3-aminofurazan-4-carboxchloridoxime by the process of diazotization, azidation and dimerization in a yield of 81%, and its structure was confirmed by IR, H NMR, C NMR, N NMR, MS and elemental analysis. The single crystal of DAZTF was cultivated and tested by X-ray single-crystal diffraction. The crystal belongs to monoclinic system, space group P2(1)/n with crystal parameters a＝1.1620(6) nm, b＝0.6977(4) nm, c＝1.4446(8) nm, α＝90°, β＝98.331(9)°, γ＝90°, V＝1.1589(11) nm, Z＝4, D＝1.743 g/cm, μ＝0.150 mm, F(000)＝608, and the final deviation factor R is 0.038. The part experimental properties of DAZTF had been obtained which m.p. was 50～52 ℃, temperature of decomposition was 204.20 ℃ (DSC), friction sensitivity was 86%～100% (90°) and impact sensitivity was 86%～100% (10 kg, 25 cm).
