In the crystal structure of the title compound, C33H39N3O10·C3H6O, the acetone mol­ecule is encapsulated into the cavity of the cryptand and fixed by two N—H...O and one C—H...O hydrogen bond. C—H...O and C—H...N inter­actions link neighbouring cryptands. The dihedral angles between the pyridine ring and the benzene rings are 86.47 (17) and 85.53 (13)°.

There are two independent mol­ecules in the asymmetric unit of the title compound, C20H17ClO3, each having an E configuration about the –C=C– bond. The dihedral angles between the two benzene rings in the two mol­ecules are 7.17 (11) and 9.82 (11)°. In both mol­ecules, the hy­droxy group is involved in an intra­molecular O—H...O hydrogen bond.
