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

In the title compound, C25H25NO7S, the molecular conformation is stabilized by intramolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds, which form S(6) and S(8) ring motifs, respectively. The molecules are bent at the S atom with a C-SO2-NH-C torsion angle of -70.86 (11)degrees. In the crystal, molecules are linked by C-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds, forming molecular layers parallel to the (100) plane. C-H center dot center dot center dot pi interactions are observed between these layers.
