Crystal structure of 2,4-di­nitro­phenyl 4-methyl­benzene­sulfonate: a new polymorph

The title compound, C(13)H(10)N(2)O(7)S, was synthesized via a nucleophilic substitution reaction between 2,4-di­nitro­phenol and p-toluene­sulfonyl chloride. This crystal structure is a polymorph of CSD entry WUVYUH [Vembu et al. (2003). Acta Cryst, E59, o378–380]. The aromatic substituents on the sulfonate group are oriented gauche to one another with a C—O—S—C torsion angle of −62.0 (3)°. The supra­molecular features that contribute to the crystal stability are offset π–π [centroid–centroid distance = 3.729 (2) Å] and multiple C—H⋯O inter­actions.
