Abstract
Three new 5-nitraminotetrazole high-nitrogen energetic salts, (NH 2NH2)+ (NATZ)- · 0. 5H 2O, (CHZ)+(NATZ)- and (en)+(NATZ) - , were synthesized and characterized by elemental analysis, infrared spectra, DSC, TG-DTG and single crystal X-ray diffraction analysis. The single crystal of (CHZ)+ (NATZ)- was cultured by slow evaporation method. The results show that the crystal belongs to monoclinic systhem with, Pn, a = 0. 37389(1)nm, b=1. 2396(5) nm, c = 0. 8699(4) nm, β= 92. 212(7)°, V = 0. 4029nm3 ; ρ= 1. 815g/cm3 ; Z= 2; F(000) = 228,L = 0. 160mm, R1= 0.0253, wR2 = 0. 0550. At a heating rate of 10K/min, the thermal decomposition process of (NH 2NH2)+ (NATZ)- · 0. 5H 2O consists of one endothermic peak without residues, while the others consist of one endothermic peak and one exothermic peak. The sensitivity properties showed that the impact sensitivity and friction sensitivity were higher, while the flame sensitivity was lower.
