sensitivities (IS = 6 J, FS = 180 N) show that it is more insensitive than CL-20, close to those of RDX and HMX. To analyze the intermolecular interaction of CL-20:MTNP, a series of theoretical analyses was employed including Hirshfeld surface analysis, non-covalent interaction plots, interaction energy calculations, and electrostatic surface potential distributions. The physicochemical performance implies that
一种新型多氮高能共晶2,4,6,8,10,12-六硝基六氮杂异纤锌矿型结构烷烃(CL-20),以1-甲基-3,4,5-三硝基吡唑(MTNP)为供体,比例为1:制备1摩尔比并通过X射线衍射表征。代替传统的芳香族供体,例如2,4,6-三硝基甲苯(TNT)和2,4,6-三硝基苯(TNB),本研究引入了多氮唑化合物。CL-20:MTNP具有1.932克cm的高晶体密度-3在293(2)K和优异的性能爆轰(ν d = 9347毫秒-1,P= 40.5 GPa),因为它具有较高的生成热,氮含量和氧平衡。此外,测得的冲击和摩擦敏感性(IS = 6 J,FS = 180 N)表明,它比CL-20更加不敏感,接近RDX和HMX。为了分析CL-20:MTNP的分子间相互作用,采用了一系列理论分析,包括Hirshfeld表面分析,非共价相互作用图,相互作用能计算和静电表面电势分布。理化性能表明,CL-20:MT
