In the title compound, C24H24Cl4N2O4S2, the dihedral angles between the central benzene ring and the pendant rings are 58.09 (10) and 62.59 (10)°. The dihedral angle between the pendant rings is 81.64 (9)°. Both sulfonamide groups lie to the same side of the central ring but the C—S—N—C torsion angles [73.09 (16) and −117.35 (14)] and S—N—C—C torsion angles [−143.80 (14) and −111.45 (16)°] differ significantly for the two pendant chains. The N atoms are close to planar (bond angle sums = 356.4 and 359.5°). In the crystal, weak C—H⋯O and C—H⋯Cl interactions link the molecules.

A mixture of N,N'-(benzene-1,3-diyldimethanediyl)bis(2,5-dichlorobenzenesulfonamide) (0.3 g; 0.5 mmol), sodium hydride (0.25 g; 0.9 mmol) and N,N-dimethylformamide (10.0 ml) was stirred in a 100-ml round bottom flask at room temperature for half an hour followed by the addition of ethyl iodide (0.15 g; 0.9 mmol). The reaction mixture was further stirred for five hours, and its completion was monitored by TLC. After completion, the contents were poured over crushed ice. The precipitated product was isolated, washed and crystallized from methanol to yield colourless block-like crystals of the title compound.
The 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) or 1.5Ueq(methyl C). The methyl groups were allowed to rotate, but not to tip, to best fit the electron density.

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 studies of symmetrical aryl sulfonamides (Ejaz et al., 2011a,b), the synthesis and structure of the title compound are described herein.
In the title compound (Fig. 1), the dihedral angles between the central (C1-C6) benzene ring and the pendant (C10-C15) and (C19-C24) rings are 58.09 (1) and 62.59 (10)°, respectively. The equivalent angle between the pendant rings is 81.64 (9)°. Both sulfonamide groups lie to the same side of the central ring, but the C10—S1—N1—C7 and C19—S2—N2—C16 torsion angles [73.09 (16) and -117.35 (14)°, respectively] and the S1—N1—C7—C2 and S2—N2—C16—C6 torsion angles [-143.80 (14) and -111.45 (16)°, respectively] differ significantly for the two pendant chains. The conformations of the ethyl side chains are also different: the S1—N1—C8—C9 and S2—N2—C17—C18 torsion angles are -89.6 (2) and -126.57 (19)°, respectively. The nitrogen atoms are close to planar (bond angle sums = 356.4 and 359.5° for N1 and N2, respectively), which seems to indicate a valence state close to sp2 hybridization, as also seen in a related structure (Ejaz et al., 2011a).
In the crystal, weak C—H···O and C—H···Cl interactions link the molecules (Table 1).
