N,N'-(Ethane-1,2-di-yl)bis-(4-chloro-benzene-sulfonamide)
Abstract:
The title mol-ecule, C(14)H(14)Cl(2)N(2)O(4)S(2), lies on an inversion center. The mol-ecule is twisted in the region of the sulfonamide group with a C-S-N-C torsion angle of -67.49 (16)°. In the crystal, mol-ecules are connected via inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonds, forming layers parallel to (100).

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
