The title compounds C17H17NO4S (I) and C17H17NO4S(II) crystallized in the monoclinic system with the space group of P21/c. The dihedral angles of 8.88(2)˚ and 10.54(13)˚ are observed between their terminal rings for I and II, respectively. Intramolecular hydrogen bonds form a pair of S(6) ring motifs in (I) and three S(6) ring motifs in (II). The crystal structure is stabilized by short intermolecular hydrogen bonds generating ring motifs of the type R22(12) (I) and R12(5) (II). Overall packing form a 3D supramolecular network in (I) and layer stacking along b axis in (II). The intermolecular interactions and their percentage of contributions were quantified for both the compounds using Hirshfeld surfaces.
