A new energetic dipotassium 3,3΄-dinitro-5,5΄-bis-1,2,4-triazole-1,1΄-diolate [K2(DNOBT)] was synthesized, and structurally characterized by elemental analysis, IR spectra, 13C NMR and single-crystal X-ray diffraction. K2(DNOBT)•2H2O crystallizes in monoclinic system, space group P21/n with a = 6.0446(10), b = 15.999(3), c = 6.4169(11) Å, β = 99.421(2)°, V = 612.21(18) Å3, Z = 4, Dc = 2.009 gcm-3, F(000) = 372, μ = 0.838 mm-1, S = 1.012, the final R = 0.0248 and wR (I > 2(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 ℃.
