Abstract: Two transition metal (Ni(Ⅱ) and Cu(Ⅱ)) complexes were synthesized using 2, 4, 6-triamino-3, 5-dinitropyridine-1-oxide ( TANPyO) as ligand and characterized by FT-IR spectroscopy, elemental analysis, DSC and TG-DTG.Effects of the two complexes on the thermal decomposition of ammonium perchlorate ( AP) were studied.The sensitivity properties of TANPyO were tested according to specifications of standardization method GJB772A-1997.Results show that the thermal decomposition proces-ses of two complexes both consist of one violent exothermic peak with metal oxides residues.The two complexes make the higher thermal decomposition temperature of AP decrease by 47.14℃and 98.24℃, the decomposition reaction accelerate and the exo-thermic quantity increase, revealing that the two complexes have good catalytic effect on the thermal decomposition of AP.The drop height of impact sensitivity is 300 cm.The friction sensitivity and electrostatic spark sensitivity are zero, showing that TANPyO is an insensitive energetic compound.
