Abstract : With the exception of the terminal benzene rings, the atoms in the title compound, C 20H 18ClN 3O 2, are approximately coplanar (r.m.s. deviation = 0.0495 Å). The benzene/chloro-benzene rings form dihedral angles of 3.02 (4) and 41.59 (5)°, respectively, with this plane. The hy-droxy, amino and carbonyl groups all lie to the same side of the mol-ecule, enabling the formation of intra-molecular O - H⋯O and N - H⋯O hydrogen bonds that close S(6) rings. The configuration about the 2-butene bond is Z. Supra-molecular chains mediated by C - H⋯Cl inter-actions and aligned along the c axis are found in the crystal packing. These assemble into layers that are connected by weak π-π inter-actions between centrosymmetrically related chloro-benzene rings [3.8156 (9) Å].
