2-[2-(2-Bromo-phen-yl)-2-oxoeth-yl]-1λ(6),2-benzothia-zole-1,1,3-trione.
The asymmetric unit of the title compound, C(15)H(10)BrNO(4)S, contains two different conformers in which the benzisothia-zole rings are essentially planar, with r.m.s. deviations of 0.012 and 0.017 Å. The mean planes of the benzene rings form dihedral angles 70.49 (13) and 72.79 (11)° with the benzisothia-zole rings. The orientation of the Br atoms in the two conformers exhibit the most pronounced difference, with opposing orientations in the two mol-ecules. The crystal structure is stabilized by π-π inter-actions between the benzene rings of the benzisothia-zole moieties of one mol-ecule and bromo-benzene rings of the other mol-ecule, with distances between the ring centroids of 3.599 (3) and 3.620 (3) Å, respectively. The crystal packing is further consolidated by pairs of weak inter-molecular C-H⋯O hydrogen bonds, which form inversion dimers.
