Abstract
In the title compound, C17H15N3O5S, the 2,3-dihydroxybenzaldehyde unit is oriented at a dihedral angles of 16.83 (10) and 78.87 (6)° with the anilinic and 5-methyl-1,2-oxazol-3-amine groups, respectively. An S(6) loop exists due to intramolecular O—H⋯N hydrogen bonding. In the crystal, inversion dimers with R 2 2(8) rings are formed due to N—H⋯N hydrogen bonding between the 5-methyl-1,2-oxazol-3-amine groups. These dimers are interlinked by O—H⋯O hydrogen bonds, forming chains along [101] and resulting in R 2 2(26) rings. π–π interactions occur between the central benzene rings with a centroid–centroid distance of 3.7928 (16) Å.
