Popis
The asymmetric unit of the title compound, C8H7Br2NO3, comprises two crystallographically independent molecules (A and B). The nitro groups are twisted from the attached benzene rings, making dihedral angles of 39.26 (9) and 35.90 (9)° in molecules A and B, respectively. In each molecule, the dibromomethyl group is orientated in such a way that the two Br atoms are tilted away from the benzene ring. An interesting features of the crystal structure is the two short Br...Br interactions which, together with intermolecular C—H...O hydrogen bonds, link the molecules into an extended three-dimensional network. The crystal structure is further stabilized by weak C—H...π interactions.
