2-Bromo-1-(3-nitro-phen-yl)ethanone.

ABSTRACT: In the title compound, C(8)H(6)BrNO(3), there are two mol-ecules, A and B, in the asymmetric unit. The nitro and ethanone groups lie close to the plane of the benzene ring and the bromine atom is twisted slightly: the dihedral angles between the mean planes of the nitro and ethanone groups and the benzene ring are 4.6?(4) (A) and 2.8?(3) (B), and 0.8?(8) (A) and 5.5?(8)° (B), respectively. An extensive array of weak C-H?O hydrogen bonds, ?-? ring stacking [centroid-centroid distances = 3.710?(5) and 3.677?(5)?Å] and short non-hydrogen Br?O and O?Br inter-molecular inter-actions [3.16?(6)and 3.06?(8)?Å] contribute to the crystal stability, forming a supermolecular three-dimensional network structure along 110. These inter-actions give rise to a variety of cyclic graph-set motifs and form inter-connected sheets in the three-dimensional structure.
