摘要：

A new energetic dipotassium 3,3?-dinitro-5,5?-bis-1,2,4-triazole-1,1?-diolate [K;（DNOBT）] was synthesized, and structurally characterized by elemental analysis, IR spectra, 13 C NMR and single-crystal X-ray diffraction. K;（DNOBT）·2H;O crystallizes in monoclinic system, space group P21/n with a=6.0446（10）, b=15.999（3）, c=6.4169（11） ?, β=99.421（2）°, V=612.21（18） ?;, Z=4, Dc=2.009 g·cm;, F（000）=372, μ=0.838 mm;, S=1.012, the final R=0.0248 and w R(I > 2σ（I）)=0.0604. Thermal decomposition of the title compound was studied by using DSC and TG-DTG, and there is primarily one exothermic decomposition process at 371.5 ℃.
