Crystal structure and Hirshfeld surface analysis of dimethyl 4-hydroxy-5,4′-dimethyl-2′-(toluene-4-sulfonylamino)biphenyl-2,3-dicarboxylate

In the title compound, C 25 H 25 NO 7 S, the molecular conformation is stabilized by intramolecular O—H���O and N—H���O hydrogen bonds, which form S(6) and S(8) ring motifs, respectively. The molecules are bent at the S atom with a C—SO � 2 —NH—C torsion angle of 70.86 (11) . In the crystal, molecules are linked by C—H���O and N—H���O hydrogen bonds, forming molecular layers parallel to the (100) plane. C—H���� interactions are observed between these layers.
