The complete molecule of the title compound, C20H20N2O4S2, is generated by crystallographic twofold symmetry, with two C atoms lying on the rotation axis. The dihedral angle between the central benzene ring and the pendant ring is 68.42 (6)° and the dihedral angle between the pendant rings is 45.11 (5)°. The torsion angles for the C—S—N—C and S—N—C—C fragments are −73.22 (15) and −150.45 (13)°, respectively. In the crystal, molecules are linked by N—H⋯O hydrogen bonds, generating corrugated (001) sheets. Aromatic π–π stacking [centroid–centroid separation = 3.8925 (12) and 3.9777 (12) Å] and weak C—H⋯O interactions also occur.

The m-xylylenediamine (0.132 ml, 1.0 mmol) was mixed with 20 ml distilled water in a 50 ml round bottom flask. Benzene sulfonyl chloride (0.255 ml, 2.0 mmol) was added while maintaining the pH of the reaction mixture at ca. 9.0 using sodium carbonate solution (3%) and the mixture was stirred for five hours. The white precipitated product was filtered, washed, dried and crystallized from methanol to generate colourless blocks of the title compound.
The N-bound H atom was located in a difference map and its position was freely refined with the constraint Uiso(H) = 1.2Ueq(N). The C-bound hydrogen atoms were placed in calculated positions (C—H = 0.93–0.97 Å) and refined as riding atoms with Uiso(H) = 1.2Ueq(C).

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. |

As part of our ongoing structural studies of sulfonamides (Khan et al., 2011), the synthesis and structure of the title compound are described herein.
The complete molecule of the title compound is generated by crystallographic twofold symmetry (Fig. 1), with atoms C9 and C11 lying on the rotation axis. The diehdral angle between the central benzene ring and the pendant ring is 68.42 (6)°. The dihedral angle between the two pendant rings is 45.11 (5)°. The conformation of the C4—S1—N1—C7 fragment is approximately gauche [-73.22 (15)°] whereas the torsion angle for S1—N1—C8—C9 of -150.45 (13)° indicates a conformation between gauche and anti. The bond-angle sum for N1 of 350.6° seems to indicate a valence state close to sp2 hybridization.
In the crystal, the molecules are linked by N—H···O hydrogen bonds (Table 1), to generate corrugated (010) sheets (Fig. 2). Weak aromatic π-π stacking [centroid-centroid separation = 3.8925 (12) and 3.9777 (12) Å] occurs between the layers and weak C—H···O interactions may help to consolidate the packing.
