| Abstract: | A new high-energy organic cesium salt,2-(dinitromethylene)-1,3-diazacyclopentane cesium salt [Cs(DNDZ)],was synthesized and structurally characterized.The crystal belongs to monoclinic system with space group P21/c and a=0.933 6(2) nm,b=0.677 42(14) nm,c=1.387 4(3) nm,β=101.173 (2)°,V=0.860 8(3) nm3,Z=4,μ=4.292 mm-1,F(000)=576,Dc=2.361 g·cm-3,R1=0.029 1,and wR2=0.077 8.Thermal behavior of Cs(DNDZ)was studied under the non-isothermal conditions by DSC and TG/DTG methods.The enthalpy,apparent activation energy and pre-exponential factor of the first exothermic decomposition reaction were -1045 J ·g-1,144.2 kJ· mol-1 and 1013.75 s-1,respectively.The critical temperature of thermal explosion (Tb) for Cs(DNDZ) is 181.48 ℃.Cs(DNDZ) presents lower thermal stability than DNDZ.CCDC:824312. |
