The syntheses and crystal structures of the isomeric 4-bromo-\it N-(2-nitro{\-}phen{\-}yl)sulfon{\-}ylbenzamide, (I), and 4-bromo-{\it N}-(4-nitro{\-}phen{\-}yl)sulfon{\-}ylbenzamide, (II), are described (mol{\-}ecular formula = C${\sb 13}$H${\sb 9}$BrN${\sb 2}$O${\sb 5}$S in each case). The asymmetric unit of (I) contains two independent mol{\-}ecules (I{\it A}) and (I{\it B}), while that of (II) contains one mol{\-}ecule. The benzoic acid aromatic ring of mol{\-}ecule (I{\it A}) is disordered due to rotation about the C${\sb ar}${---}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){$^\circ$} in (I{\it A}) and 65.22(19){$^\circ$} in (I{\it B}), while in (II), the corresponding value is 56.7(7){$^\circ$}. In the crystals of (I) and (II), N{---}H{$\cdots$}O, C{---}H{$\cdots$}O and C{---}H{$\cdots$}{$\pi$} inter{\-}actions generate three-dimensional networks.
