In the crystal structure of the title compound, C 33 H 39 N 3 O 10 ·C 3 H 6 O,  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)°.
