2-Nitro-p-phenylene bis(toluenesulfonate)

Abstract

In the molecule of the title compound, C20H17NO8S2, the two toluene rings are oriented at a dihedral angle of 3.65 (4)°, while the nitrophenyl ring is oriented at dihedral angles of 44.39 (3) and 47.44 (3)° with respect to the toluene rings. An intramolecular C—H...O hydrogen bond results in the formation of a five-membered ring, which adopts an envelope conformation. In the crystal structure, intermolecular C—H...O hydrogen bonds link the molecules. There is a π–π contact between the toluene rings [centroid–centroid distance = 4.035 (1) Å].
