1-(4-Bromophenyl)-2-methyl-4-nitro-1H-imidazole: bifurcated Br...O halogen-nitro bonds.
The crystal packing of the title compound, C(10)H(8)BrN(3)O(2), is determined mainly by relatively strong bifurcated C-Br...O halogen-nitro bonds. Both O atoms are involved in this interaction in an almost symmetrical manner and the difference [0.078 (3) A] between the Br...O contact lengths is one of the smallest found in similar compounds. Halogen bonds and weak hydrogen bonds connect molecules into layers which are stacked along the [100] direction.
