Two intramolecular N - H⋯O and N - H⋯N hydrogen bonds occur, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C - H⋯O hydrogen bonds link the molecules into inversion dimers with R 2 2(14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C - H⋯π and π-π-stacking interactions [centroid-to-centroid distances = 3.631(2) and 3.631(2)Å], forming a three-dimensional network. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from H⋯H (39.3%), C⋯H/H⋯C (18.0%), O⋯H/H⋯O (15.6) and S⋯H/H⋯S (10.2%) interactions.true1,3-benzoxazole ring system | Crystal structure | Dimers | Hirshfeld surface analysis | Hydrogen bondingArticle10.1107/S20569890190129082-s2.0-85073053164
