title: N-(4-Chloro-2-nitro-phen-yl)methane-sulfonamide.
abstract: The title compound, C(7)H(7)ClN(2)O(4)S, is of inter-est as a precursor to biologically active substituted quinolines. Its structure resembles those of the previously reported N-phenyl-methane sulfonamide and its 4-nitro, 4-fluoro and 4-bromo derivatives, with slightly different geometric parameters. An intra-molecular N-H⋯O hydrogen bond gives rise to a six-membered ring. Inter-molecular C-H⋯O contacts stabilize the crystal packing.
