1-Dibromomethyl-4-methoxy-2-nitrobenzene

Abstract

The asymmetric unit of the title compound, C<inf>8</inf>H <inf>7</inf>Br<inf>2</inf>NO<inf>3</inf>, 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 mol-ecule, the dibromo-methyl group is orientated in such a way that the two Br atoms are tilted away from the benzene ring. An inter-esting features of the crystal structure is the two short Br?Br inter-actions which, together with inter-molecular C - H?O hydrogen bonds, link the molecules into an extended three-dimensional network. The crystal structure is further stabilized by weak C - H?? inter-actions. © Fun et al. 2009.
