4,4′-Dichloro-N,N′-(o-phenylene)dibenzenesulfonamide

Abstract

The title compound, C18H14Cl2N2O4S2, is a diamine that is a precursor to a quinonoid bidentate redox-active ligand. The dihedral angles between the central phenyl ring and the end rings are 87.5(1) and 60.7(1)°, while the two end rings make a dihedral angle of 82.5(1)°. The crystal structure is stabilized by two weak intermolecular N—H...O hydrogen bonds, as well as one intramolecular C—H...O and one N—H...N hydrogen bond.
