CRYSTAL-STRUCTURE OF N-(4-NITROPHENYL)-N-PHENYLSULFONAMIDE

The crystal structure of N-(4-nitrophenyl)-N-phenylsulfonamide (C18H14 N2O4S), a derivative of sulfonamide, has been determined by X-ray diff raction method using CuKalpha radiation. The compound crystallizes in the monoclinic space group P2(1)/n, with a = 24.463(1), b = 5.745(2), c = 11.428(3) angstrom and beta = 94.39(2)-degrees. The structure was solved by direct methods and refined by full-matrix least squares to a final R value of 0.045 with 3032 unique reflections. The dihedral ang le between the substituents phenyl ring B and the phenyl A is 94.7(3)- degrees. The S atom is in the usual distorted tetrahedral configuratio n.
