Sulfanilamide (0.344 g, 2 mmol) in ethanol (20 ml) was mixed with 5-bromosalicylaldehyde (0.402 g, 2 mmol) in ethanol (10 ml). The resultant mixture was refluxed for 4 h by monitoring through TLC. During refluxing the solution turned from colorless to orange yellow. After completion of reaction, it was cooled to room temperature, filtered and volume reduced to about one-third using rotary evaporator. It was then allowed to stand for 7 days at room temperature. After which a crystallized product was formed that was filtered, washed with ethanol (2 × 5 ml), dried and recrystallized in a mixture of methanol and ethanol (1:1) to afford shiny orange yellow prisms of (I).
The coordinates of H-atoms of the NH2 group were refined. The other H-atoms were positioned geometrically with O—H = 0.82, C—H = 0.93 Å for aromatic H atoms and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C, N, O), where x = 1.2 for all H atoms.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

As part of our ongoing studies of sulfonamides, we now report the structure of the title compound, (I). The crystal structure of (II) 4-{[(E)-(5-chloro-2-hydroxyphenyl) methylidene]amino}benzenesulfonamide (Chohan et al., 2009) has been reported which differs from (I) due to chloro substitution instead of bromo.
In (I), the benzene rings A (C1—C6) of 5-bromosalicylaldehyde and B (C8—C13) of sulfanilamide are oriented at a dihedral angle of 12.03 (36)°. The Br1 and S1 atoms are at a distance of -0.016 (8) and -0.159 (9) A° from the mean square planes of rings A and B, respectively. There exist two intramolecular H-bonds (Table 1, Fig. 1) forming S(5) and S(6) ring motifs (Bernstein et al., 1995). Three intermolecular H-bondings (Table 1) link the molecules in polymeric nature extending along the b axis (Fig. 2) and forming R33(10) and R21(8) ring motifs.
