Three kinds of energetic complexes,Co(CHZ)4(PA)2·3H2O,Cu(CHZ)4(PA)2·4H2O and Pb(CHZ)2(PA)2·4H2O(CHZ= carbodihydrazide,PA=picric acid),were synthesized with carbohydrazide,picric acid and corresponding metallic(Co,Cu,Pb) salts.The molecular formulas of these coordination compounds were derived by using elemental analyses and FTIR techniques.The friction,impact and flame sensitivities of the complexes were tested followed by the standard methods.The effects of the energetic complexes on the thermal decomposition of CL-20 were studied by means of DSC and TG-DTG techniques.The results show that the addition of those complexes make the onset temperature and peak temperature of CL-20 shift to low temperature.The kinetic parameters Ea and A of the first exothermic decomposition process for complexes/CL-20 mixture were calculated by Kissingér′s method and Ozawa-Doylés method.Cu(CHZ)(PA) and(CHZ)(PA) make the Ea value of the exothermic processes of CL-20 decrease from 222.8kJ/mol to 186.6kJ/mol and 183.0kJ/mol.
