N-(2-Formyl-phen-yl)-4-meth-oxy-N-(4-meth-oxy-phenyl-sulfon-yl)benzene-sulfonamide
Abstract:
In the title compound, C(21)H(19)NO(7)S(2), the dihedral angles between the formyl-phenyl ring and the two meth-oxy-phenyl rings are 33.87 (9) and 41.00 (10)°. The S atoms have a distorted tetra-hedral geometry and the N atom shows a trigonally planar [r.m.s. deviation = 0.0437 (13) Å] coordination. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

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...
