In the title mol­ecule, C12H7BrCl2O3S, the dihedral angle between the two benzene rings is 55.18 (5)°. The notable inter­molecular contacts include C—H⋯O and π–π inter­actions [centroid–centroid distances = 4.037 (1) and 3.349 (1) Å].

Comment top

Aromatic sulfonates are used in monitoring the merging of lipids (Yachi et al., 1989) and in many other fields (Spungin et al., 1992; Tharakan et al.,1992; Alford et al., 1991; Jiang et al., 1990; Narayanan & Krakow, 1983). An X-ray study of the title compound was undertaken in order to determine its crystal and molecular structure owing to the biological importance of its analogues. The molecular structure is shown in Fig. 1.

The C4–S–O3–C7 torsion angle of 65.86 (14)° corresponds to +synclinal conformation; as expected the dihedral angle between the mean planes of the 2,4-dichlorophenyl and bromobenzene rings of 55.18 (5)° shows that the two rings are not coplanar. This is similar to the situation reported by us for other aromatic sulfonates (Vembu et al. 2007 and references cited therein).

The crystal structure exhibits weak intermolecular C—H···O interactions (Desiraju & Steiner, 1999) (Table 1). There are two face to face π···π aromatic stacking interactions. The coordinates of Cg1···Cg1 (-x, 1 - y, 1 - z) at 4.037Å are α = 0.00, β = 24.13, γ = 24.13, the two perpendicular distances involving the aromatic rings being 3.684 Å. The coordinates of Cg2···Cg2 (-1 - x, -y, 2 - z) at 3.751Å are α = 0.03, β = 26.79, γ = 26.79, the two perpendicular distances involving the aromatic rings being 3.349 Å. Cg1 is the centroid of the aromatic ring formed by the atoms C1, C2, C3, C4, C5 & C6, Cg2 is the centroid of the aromatic ring formed by the atoms C7, C8, C9, C10, C11 & C12. α is the dihedral angle between the planes of the two aromatic rings, β is the angle of the aromatic ring formed by the atoms C1—C6 through the aromatic ring formed by the atoms C7—C12, γ is the angle of the vector through the centroids of the planes of the two aromatic rings and normal to the plane of the aromatic ring formed by C7—C12 (Spek, 2009).

Experimental top

4-Bromobenzenesulfonyl chloride (10 mmol), dissolved in acetone (10 ml), was added dropwise to 2,4-dichlorophenol (10 mmol) in aqueous NaOH (8 ml, 5%) with constant stirring. The precipitate (6.5 mmol, yield 65%) was filtered and recrystallized from aqueous ethanol.

All H-atoms were located in difference maps and their positions and isotropic displacement parameters freely refined.

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