Comment top

The chemistry of N-halo arylsulfonamides is of interest in synthetic, mechanistic, analytical and biological chemistry (Gowda et al., 2005; Gowda & Shetty, 2004; Usha & Gowda, 2006). In the present work, the structure of sodium N-bromo-4-chlorobenzenesulfonamde has been determined to explore the effect substituent on the solid state structures of sulfonamides and N-halo arylsulfonamides (Gowda et al., 2003; Gowda, Foro et al., 2007; Gowda, Jyothi et al., 2007; Gowda, Kozisek et al., 2007; Gowda, Savitha et al., 2007; Gowda, Srilatha et al., 2007; Gowda, Usha et al., 2007). The structure of of the title compound (Fig. 1) resembles those of sodium N-bromo-benzenesulfonamde (Gowda, Usha et al., 2007) and sodium N-chloro-4-chlorobenzenesulfonamde (Gowda, Jyothi et al., 2007). The sodium ion shows octahedral coordination by three O atoms of water molecules and by three sulfonyl O atoms of three different N-bromobenzenesulfonamide anions. There is no interaction between the nitrogen and sodium atoms in the molecule and there are two molecules in the asymmetric unit. The S—N distances of N1—S1, 1.574 (5)Å and N2—S2 1.579 (4)Å are consistent with a S—N double bond. There are several hydrogen bonds in the crystal structure.

Experimental top

The title compound was prepared according to the literature method (Gowda & Usha, 2003). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra (Gowda & Usha, 2003). Single crystals of the title compound were obtained from its aqueous solution and used for X-ray diffraction studies at room temperature.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
