The structure of the title compound, Na+·C6H4BrFNO2S·1.5H2O, like other sodium N-bromo­aryl­fonamidates, crystallizes with two cations, two anions and three water mol­ecules in the asymmetric unit. The sodium cation shows octa­hedral coordination by three O atoms of three different water mol­ecules and by three sulfonyl O atoms of three different N-bromo-4-fluoro­benzene­sulfonamide anions. There is no inter­action between the nitro­gen atom and sodium ion in the mol­ecule. The S—N distance of 1.591 (6) Å is consistent with an S=N double bond. The crystal structure is stabilized by O—H...N hydrogen bonds.

The chemistry of N-bromo-arylsulfonamides is of interest due to their distinct physical, chemical and biological properties (Usha & Gowda, 2006). In the present work, the structure of sodium N-bromo-4-fluoro- benzenesulfonamidate (NaNB4FBSA) has been determined to study the substituent effects on the solid state structures of arylsulfonamides and N-halo arylsulfonamidates (Gowda, Jyothi et al., 2007; Gowda et al., 2007a,b; Gowda, Usha et al., 2007). The structure of NaNB4FBSA (Fig. 1) is similar to those of sodium N-bromo-benzenesulfonamidate(NaNBBSA)(Gowda, Usha et al., 2007) and sodium N-bromo-4-chloro-benzenesulfonamidate (NaNB4CBSA)(Gowda, Kožíšek et al., 2007a) and sodium N-chloro-arylsulfonamidates (George et al., 2000; Gowda, Jyothi et al., 2007). NaNB4FBSA crystallizes with two cations, two anions and three water molecules in the asymmetric unit. The sodium ion shows octahedral coordination by three O atoms of three different water molecules and by three sulfonyl O atoms of three different N-bromo-4-fluoro-benzenesulfonamide anions. There is no interaction between the nitrogen and sodium ions in the molecule. The S—N distances of N1—S1, 1.591 (6) Å is consistent with a S—N double bond and in agreement with those observed with NaNBBSA, NaNB4CBSA and sodium N-chloro- arylsulfonamidates. The occurrence of O—H···N hydrogen bonds between the wat er molecules and N atom associated with the presence of Na+ result in the formation of thick layered structure parallel to the (0 0 1) plane (Table 1, Fig. 1). This thick layer may be described as build up from an internal layer containing Na atoms and water molecules sandwiched by the benzenesulfonamidate with the fluorobenzene pointing outward.

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 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 mutual distance restrained to 1.35 (5) Å and O—H bond length 0.82 (5) Å. No restraints were applied to 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.
