摘　　要：A novel energetic ionic salt,hydroxylammonium potassium 3,3?-dinitro-5,5?-bis-1,2,4-triazole-1,1?-diolate dihydrate[(NH3OH)2K(DNOBT)1.5?2H2O],was synthesized and structurally characterized by elemental analysis,IR spectra,13C NMR and single-crystal X-ray diffraction.(NH3OH)2K(DNOBT)1.5?2H2O crystallizes in triclinic system,space group P with a=7.9212(6),b=9.1924(7),c=14.2549(15)?,a=103.917(2)°,β=99.736(2)°,g=104.8110(10)°,V=944.16(14)?^3,Z=2,Dc=1.855 g/cm^3,F(000)=538,μ=0.386 mm^-1,S=1.070,the final R=0.0525 and wR(I>2s(I))=0.1593.Thermal decomposition of(NH3OH)2K(DNOBT)1.5?2H2O and its intermediate potassium 1?-hydroxy-3,3?-dinitro-5,5?-bis-1,2,4-triazole-1-olate monohydrate[K(HDNOBT)?H2O]was studied by using DSC and TG-DTG.It was found that(NH3OH)2K(DNOBT)1.5?2H2O,which has primarily one exothermic decomposition process at 248.2℃,has better thermal stability than K(HDNOBT)?H2O which is decomposed at 210.9℃.
