4,4'-Sulfonylbis[N-(4-nitrophenylmethylene)benzenamine]: whole-molecule disorder.

The crystal structure of the title compound, C(26)H(18)N(4)O(6)S, determined from synchrotron data with a small crystal, is characterized by the presence of whole-molecule disorder. In each molecule, the two planar portions are approximately perpendicular to one another and there are short intermolecular contacts between the nitro groups.
