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