A new energetic complex, Co(2,3鈥?bpt)₃路H₂O (1) (2,3鈥?Hbpt = 3-(2-pyridyl)-5-(3鈥?pyridyl)-1H-1,2,4-triazole), was synthesized and characterized by single crystal X-ray diffraction method. Crystallographic data are as follows: triclinic, P1̅ space group, a = 10.323(2) 脜, b = 11.261(2) 脜, c = 16.139(3) 脜, 伪 = 89.022(3)掳, 尾 = 71.794(2)掳, 纬 = 66.990(2)掳, Z = 2. In addition, the thermal analysis of Co(2,3鈥?bpt)₃路H₂O has been performed by thermogravimetric-differential thermogravimetric (TG-DTG) techniques. The thermal decomposition of ammonium perchlorate (AP) with complex 1 was explored by differential scanning calorimetry (DSC) over the temperature range from (323 to 773) K. AP is completely decomposed in a shorter time in the presence of complex 1, and the decomposition heat of the mixture is 2.034 kJ路g^鈥?, significantly higher than pure AP. By Kissinger's method, the ratio of E_a/ln(A) is 12.66 for the mixture, which indicates that complex 1 shows good catalytic activity toward AP decomposition.
