In the title compound, C22H23NO4S2, the dihedral angles between the dimethylphenyl ring and the two methylphenyl rings are 41.19 (15) and 20.50 (17)°; the dihedral angle between the methylphenyl rings is 48.11 (14)°. The C—N—S—C torsion angles are −87.6 (2) and 77.43 (18)°. The only possible directional interactions in the crystal are very weak C—H⋯π interactions and very weak π–π stacking between parallel methylphenyl rings [centroid-to-centroid separation = 4.010 (2) Å and slippage = 1.987 Å].

0.10 g of 2,3-dimethyl aniline was dissolved in 15 ml dichloromethane and 0.157 g of toulene sulfonyl chloride was added. The mixture was stirred at room temperature overnight and the pH was maintained at 8–9 with triethylamine. On completion of the reaction (after TLC), 1 M HCl solution was added and the organic layer was separated and allowed to evaporate at room temperature to generate light-brown crystals in 97% yield. Yellow blocks were recrystallized from ethanol solution.
The H atoms were placed in calculated positions (C—H = 0.93–0.96 Å) and refined as riding. The constraint Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C) was applied. The methyl groups were allowed to rotate, but not to tip, to best fit the electron density.
Rather than the intended product of 4-methyl-N-(2,3-dimethylphenyl)benzenesulfonamide, the title `double' sulfonamide (in which both amine N—N bonds have been replaced by N—S bonds), (I), (Fig. 1) was unexpectedly prepared. A similar double sulfonamide and previous related structures are described by Mughal et al. (2012).
The molecule of (I) cannot possess any π system of the C1–C6 ring and the C1—N1 bond length of 1.452 (3) Å is that expected for a C—N single bond.
due to the two methyl groups of the xylene ring. If these are neglected, the rest of the molecule possesses approximate local twofold symmetry about the C1—N1 axis. The dihedral angles between the o-xylene ring (C1–C6) and the C9–C14 and C15–C20 toluyl rings are 41.19 (15) and 20.50 (17)°, respectively; the dihedral angle between the toluyl rings is 48.11 (14)°. The sulfonamide torsion angles in (I) are -87.6 (2)(2)° for C1—N1—S1—C9 and 77.43 (18)° for C1—N1—S2—C16. The bond-angle sum for N1 in (I) of 359.4° implies sp2 for the N atom. However, its (presumed) unhybridized p orbital is almost orthogonal to the aromaticThe only direction interactions in the crystal of (I) are a possible very weak C—H···π bond (Table 1) and aromatic π–π stacking between inversion-related pairs of C9–C14 rings [centroid–centroid separation = 4.010 (2) Å; slippage = 1.987 Å].

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. |

Rather than the intended product of 4-methyl-N-(2,3-dimethylphenyl)benzenesulfonamide, the title `double' sulfonamide (in which both amine N—N bonds have been replaced by N—S bonds), (I), (Fig. 1) was unexpectedly prepared. A similar double sulfonamide and previous related structures are described by Mughal et al. (2012).
The molecule of (I) cannot possess any local symmetry due to the two methyl groups of the xylene ring. If these are neglected, the rest of the molecule possesses approximate local twofold symmetry about the C1—N1 axis. The dihedral angles between the o-xylene ring (C1–C6) and the C9–C14 and C15–C20 toluyl rings are 41.19 (15) and 20.50 (17)°, respectively; the dihedral angle between the toluyl rings is 48.11 (14)°. The sulfonamide torsion angles in (I) are -87.6 (2)(2)° for C1—N1—S1—C9 and 77.43 (18)° for C1—N1—S2—C16. The bond-angle sum for N1 in (I) of 359.4° implies sp2 hybridization for the N atom. However, its (presumed) unhybridized p orbital is almost orthogonal to the aromatic π system of the C1–C6 ring and the C1—N1 bond length of 1.452 (3) Å is that expected for a C—N single bond.
The only direction interactions in the crystal of (I) are a possible very weak C—H···π bond (Table 1) and aromatic π–π stacking between inversion-related pairs of C9–C14 rings [centroid–centroid separation = 4.010 (2) Å; slippage = 1.987 Å].
