摘要:
用1,1-二氨基-2,2-二硝基乙烯的钾盐K(FOX-7)·H2O和硝酸铜在氨水体系中合成了Cu(NH3)2(FOX7)2并培养得到了单晶。该晶体为单斜晶系,空间群P21/c,a=0.68818(7)nm, b=0.73083(8)nm, c=1.31966(14)nm, β=95.986°, V=0.66009(12)nm,Dc=1.972g/cm,u=0.862mm,F(000)=199,Z=2,R1=0.0344 ,wR2= 0.0989。利用DSC研究了Cu(NH3)2(FOX-7)2的热分解行为。结果表明,Cu(NH3)2(FOX-7)2第一放热分解过程的放热焓、表观活化能、指前因子分别为-439.0J/g,140.2kJ/mol和14.78s-1,热爆炸的临界温度为152.86℃,热稳定性低于FOX-7。
Abstract:

A metal coordination compound,Cu(NH3)2(FOX-7)2,wassynthesized by mixing 1,1-diamino-2,2-dinitroethylene potassium salt[K(FOX-7)·H2O]and Cu(NO3)2·3H2O in aquaammonia. Single crystals suitable for X-ray measurement were obtained by slowevaporation in aqua ammonia at room temperature.Crystals of Cu(CH3)2(FOX-7)2revealed the following parameters:monoclinic,space group P21/c,a=0.68818(7)nm, b=0.73083(8)nm, c=1.31966(14) nm,β=95.986°,V=0.66009(12)nm3,Dc=1.972g/cm3,μ=0.862mm-1F(000)=199Z=2R1=0.0344,wR2=0.0989.Thermal decomposition behavior of Cu(NH3)2(FOX-7)2was studied under the non-isothermal conditions by DSC method. Theenthalpy, apparent activation energy and pre-exponential constant of the firstexothermic decomposition reaction are -439.0J/g,140.2kJ/mol and 14.78s-1, respectively. The critical temperature of thermal explosion forCu(NH3)2(FOX-7)2 is 152.86 .Cu(NH3)2(FOX-7)2 presents lowerthermal stability than FOX-7.
