The energetic material, 3-nitro-1,5-bis(4,4-dimethyl azide)-1,2,3-triazolyl-3-azapentane (NDTAP), was firstly synthesized by means of Click Chemistry using 1,5-diazido-3-nitrazapentane as main material. The structure of NDTAP was confirmed by IR, H-1 NMR, and C-13 NMR spectroscopy; mass spectrometry, and elemental analysis. The crystal structure of NDTAP was determined by X-ray diffraction. It belongs to monoclinic system, space group C2/c with crystal parameters a=1.7285(8)nm, b=0.6061(3)nm, c=1.6712(8)nm, =104.846(8)degrees, V=1.6924(13)nm(3), Z=8, =0.109mm(-1), F(000)=752, and D-c=1.422gcm(-3). The thermal behavior and non-isothermal decomposition kinetics of NDTAP were studied with DSC and TG-DTG methods. The self-accelerating decomposition temperature and critical temperature of thermal explosion are 195.5 and 208.2 degrees C, respectively. NDTAP presents good thermal stability and is insensitive.
