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（3）nm,Dc=0.6563（1）nm,V=0.6982（3）nm^3,Z=4,Dc=1.637g·cm^-3,μ=0.15mm^-1,F（000）=352. The impact and friction insenstitvity of 4,5-MDNI were tested by GIB772 -1997 method. 4.5-MDNI is insensitive to impact and friction and close to TATB.
