In the title compound, Na+·C6H5BrNO2S·1.5H2O, there is no inter­action between the N atom and the Na+ cation, and the Na cation exhibits octa­hedral coordination by three O atoms from water mol­ecules and by three sulfonyl O atoms of three different N-bromo­benzene­sulfonamide anions. The S—N distance of 1.578 (4) Å is consistent with an S=N double bond, similar to the distance of 1.582 (5) Å observed for the corresponding N-chloro compound. A two-dimensional polymeric layer runs parallel to the ab plane. The water mol­ecules participate in O—H...N hydrogen bonds.

The chemistry of arylsulfonamides and their N-halo compounds is of interest as they show diverse physical, chemical and biological properties. Thus N-halo arylsulfonamides are 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- benzenesulfonamde (NaNBBSA) has been determined to explore the effects substitution 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).

The structure of NaNBBSA (Fig. 1) resembles those of sodium N-chloro- arylsulfonamdes (George et al., 2000; Gowda, Foro et al., 2007; Gowda, Jyothi et al., 2007; Gowda, Savitha et al., 2007; Gowda, Srilatha et al., 2007; Olmstead & Power, 1986). NaNBBSA is the parent or unsubstituted N-bromo-arylsulphonamide. The structure confirms that there is no interaction between the nitrogen and sodium atoms. The sodium ion exhibits octahedral coordination by three O atoms from water molecules and by three sulfonyl O atoms of three different N-bromobenzenesulfonamide anions. The S—N distance of 1.578 (4)Å is consistent with a S—N double bond, similar to the distance of 1.582 (5)Å observed with the corresponding N-chloro compound. Packing diagram of the title compound involving hydrogen bonds is shown in Fig.2.

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.

Refinement top

H atoms of the benzene ring were positioned geometrically and refined using a riding model with C—H = 0.93 Å and with Uiso(H) = 1.2 Ueq(C). H atoms of the water molecules (O3w, O4w) were visible in difference map and were subsequently treated as riding with O—H bond length restrained to 0.85 (1) Å and mutual distance of H atoms 1.35 (1) Å. No restraints were applied for non-hydrogen atoms.

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.
