title: N,N'-Bis(3-methylbut-2-enyl)-N,N'-(1,4-phenylene)dibenzenesulfonamide.
abstract: The complete mol-ecule of the title compound, C(28)H(32)N(2)O(4)S(2), is generated by a crystallographic inversion centre. The dihedral angle between the central and pendant aromatic rings is 46.78 (7)°. The C(ar)-S-N-C(ar) (ar = aromatic) torsion angle is 73.64 (15)° and the bond-angle sum for the N atom is 350.4°. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming a two-dimensional network lying parallel to the bc plane.
