Abstract: The title compound is a new aminocoumarin derivative, C17H13NO4, and was synthesized by the condensation of 2-aminophenol and 3-acetyl-4-hydroxycoumarin. An intramolecular N-HO hydrogen bond generates an S(6) ring motif. In the crystal, the molecules are linked into chains extending in the  direction by O-HO hydrogen bonds. There is also a - stacking interaction between the bicyclic coumarin fragment and the phenol ring [centroid-centroid distance = 3.7510 (14) Å], and these ring systems form between them a dihedral angle of 53.3 (2)°. Intermolecular hydrogen bond C-HO hydrogen bonding is also observed in the interconnection of the crystal packing.
