, the dihedral angle between the terminal six-membered rings being 29.46 (10)°; the linked five- and six-membered rings are coplanar [1.30 (11)°]. The carbonyl O atom accepts intramolecular hydrogen bonds from the adjacent hydroxy and amine groups. The three-dimensional crystal packing is achieved through C—H⋯π interactions.
