, adjacent molecules are arranged into centrosymmetric dimers through pairs of intermolecular O—H⋯O interactions. Intermolecular N—H⋯O hydrogen bonds link the dimers into a layer parallel to the
bc
plane. In the layer, molecules are packed in a face-to-face π-stacked arrangment, showing π–π stacking interactions between the benzene rings with a centroid–centroid distance of 3.6884 (8) Å.
