Abstract

A new energetic salt of 2, 4-dinitroimidazole ([(DNI)NH2 (CH3)2]) was synthesized with yield of 62.7% by using 2, 4-dinitroimidazole as starting materials. The structure of [(DNI)NH2 (CH3)2] was characterized by IR, elemental analysis, fourcircle single crystal X-ray diffraction NMR. Results show that the crystal of title compound belongs to monoclinic system, space group C2/c with a=31.403(5) Å, b=6.7133(7) Å, c=22.769(4) Å, α= 90.00°, β=126.80(3)°, γ=90.00°, V=3843.6(10) Å3, Z=16, Dc=1.404 g ·cm-3, F(000) = 1696.0, μ(MoKα) = 0.121 mm-1. The molecule packing of [(DNI)NH2 (CH3)2] is not compacted. Intra molecular and intermolecular hydrogen bonds are weak and the density is lower. Thermal properties were tested by TG-DSC. Results reveal that the [(DNI)NH2 (CH3)2] shows good thermal stability.
