title: N,N'-Diallyl-2,2',5,5'-tetra-chloro-N,N'-[1,3-phenyl-enebis(methyl-ene)]dibenzene-sulfonamide.
abstract: In the title compound, C(26)H(24)Cl(4)N(2)O(4)S(2), the dihedral angles between the central benzene ring and the pendant rings are 70.07 (12) and 59.07 (12)°. The equivalent angle between the pendant rings is 79.24 (12)°. Both sulfonamide groups lie to the same side of the central ring but the pendant chains have very different conformations, as indicated by their C-S-N-C torsion angles [104.66 (17) and -76.35 (19)°] and S-N-C-C torsion angles [129.61 (17) and 147.10 (17)°]. Both N atoms are close to planar (bond angle sums = 359.0 and 354.8°). In the crystal, inversion dimers are formed via a pair of weak C-H⋯O inter-actions which generate R(2) (2)(22) loops.
