【 摘 要 】

Two new high-nitrogen energetic compounds ZTO·2H2O and ZTO(phen)·H2O have been synthesized (where ZTO = 4,4-azo-1,2,4-triazol-5-one and phen = 1,10-phenanthroline). The crystal structure, elemental analysis and IR spectroscopy are presented. Compound 1 ZTO·2H2O crystallizes in the orthorhombic crystal system with space group Pnna and compound 2 ZTO(phen)·H2O in the triclinic crystal system with space group P-1. In ZTO(phen)·H2O, there is intermolecular hydrogen bonds between the -NH group of ZTO molecule (as donor) and N atom of phen molecule (as acceptor). Thermal decomposition process is studied by applying the differential scanning calorimetry (DSC) and thermo thermogravimetric differential analysis (TG-DTG). The DSC curve shows that there is one exothermic peak in ZTO·2H2O and ZTO(phen)·H2O, respectively. The critical temperature of thermal explosion (Tb) for ZTO·2H2O and ZTO(phen)·H2O is 282.21 oC and 195.94 oC, respectively.
