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)°.
