N,N′-Diethyl-N,N′-[1,3-phenylenebis(methylene)] dibenzenesulfonamide

In the title compound, C₂₄H₂₈N₂O ₄S₂, the dihedral angles between the central benzene ring and the pendant rings are 77.44 (11) and 79.23 (10)°, and the dihedral angle between the pendant rings is 23.31 (12)°. Both sulfonamide groups project to the same side of the central benzene ring and the mol-ecule has approximate non-crystallographic mirror symmetry. One of the ethyl side chains is disordered over two sets of sites in a 0.526 (14):0.474 (14) ratio. In the crystal, inversion dimers linked by pairs of weak C - H⋯O inter-actions occur, generating R₂ ²(28) loops.
