Source of material
All of reagents were purchased with analysis grade. In representative experiments, 3.39 g (30 mmol) 2-nitroimidazole were dissolved in 15 mL N,N-dimethylformamide (DMF), then 4.26 g (30 mmol) methyl iodide and 1.68 g (30 mmol) potassium hydroxide (KOH) were added the target compound were obtained by reaction at 353 K for 3 h. Then cooled to room temperature and the crystals of the title compound were obtained by slow evaporation at 293 K.
Experimental details
Using Olex2 [2], the structure was solved with the XT [3] structure solution program using Intrinsic Phasing and refined with the ShelXL [4] refinement package . All H atoms were positioned geometrically and treated as riding, Uiso(H) = 1.2Ueq(C).
Comment
Many imidazoles have been studied in recent years [5, 6], even as anticancer agents and inhibitors [7], [8], [9]. The title compound 1-methyl-2-nitroimidazol is expected to have high research value. Here we report the crystal structure of the title compound (cf. the figure).
The asymmetric unit of the title structure contains one target molecule (see the figure). All geometric parameters in the title molecule are in the expected ranges [10].
