1-甲基-4,5-二硝基咪唑的晶体结构与感度性能

摘要

制备了1-甲基-4,5-二硝基咪唑(4,5-MDNI),培养了4,5-MDNI的单晶.用X射线衍射仪测定了单晶结构.结果表明,该晶体属于正交晶系,空间群为Pna2(1)/n.晶体学参数为:a=0.8412(2) nm,b=1.2646(3) nm,Dc=0.6563(1) nm,V=0.6982(3) nm3,Z=4,Dc=1.637 g·cm -3,μ =0.15 mm-1,F(000)=352.采用GJB772A-1997方法测试了4,5-MDNI的撞击感度和摩擦感度均为0,表明,4,5-MDNI对撞击和摩擦是不敏感的,接近TATB的撞击/摩擦不敏感性水平.%1-Methy-4,5-dinitroimidazole(4,5-MDNI) was prepared. The single crystal of 4,5-MDNI was cultivated. The single crystal structure was determined by a X-ray diffractometer. The results show that the crystal is orthorhombic, space group Pna2(1 )/n with crystal parameters of: a =0.8412(2) nm, b= 1.2646(1 ) nm,c= 0.6563(1 ) nm, V =0.6982 (3) nm3,Z=4, Dc =1.637 g ? Cm-3 ,μ = 0. 15 mm-1 and F(000) =352. The impact and friction insenstitvity of 4,5-MDNI were tested by GJB772 -1997 method. 4,5-MDNI is insensitive to impact and friction and close to TATB.
