The 4-nitroimidazolium perchlorate was prepared by the reaction of 4-nitroimidazole and perchloric acid aqueous solution to cultivate the single crystal of the complex. The structure of the complex was characterized by elemental analysis, infrared spectroscopy and single crystal X-ray diffraction. The results show that the crystal belongs to the orthorhombic system with space group Pca21, cell parameters a = 1.069 4 (6) nm, b = 0.656 2 (4) nm, c = 1.04 6 6 9 0.0 0 °, V = 0.7 3 4 4 (7) n m3, Dc = 1.931 g / cm3, Z = 4, F (000) = 432, R1 = 0.029 2, w R2 = 0.049 5. The thermal decomposition temperature of the compound is 175 ℃, and the impact, friction, flame are insensitive.
