The syntheses and crystal structures of the isomeric 4-bromo-N-[(2-nitrophenyl)
sulfonyl]benzamide, (I), and 4-bromo-N-[(4-nitrophenyl)sulfonyl]benzamide,
(II), are described (molecular formula = C13H9BrN2O5S in each case). The
asymmetric unit of (I) contains two independent molecules [(IA) and (IB)],
while that of (II) contains one molecule. The benzoic acid aromatic ring of
molecule (IA) is disordered due to rotation about the Car—C( O) bond over
two orientations in a 0.525 (9):0.475 (9) ratio. The dihedral angle between the
benzene rings is 85.9 (3) in (IA) and 65.22 (19) in (IB), while in (II), the
corresponding value is 56.7 (7). In the crystals of (I) and (II), N—H  O, C—
H  O and C—H   interactions generate three-dimensional networks.
