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-HO and one C-HO hydrogen bond. C-HO and C-HN interactions link neighbouring cryptands. The dihedral angles between the pyridine ring and the benzene rings are 86.47 (17) and 85.53 (13)°.
Cryptands have been utilized as hosts to form supramolecular assemblies, see: Balzani et al. (2000). Crown ether-based cryptands can form more stable supramolecular complexes with paraquat, paraquat derivatives, diquat and secondary ammonium salts than the corresponding simple crown ethers by virtue of multiple non-covalent interactions, see: Huang et al. (2005). The title compound was obtained by the reaction of bis(5-aminomethyl-1,3-phenylene)-26-crown-8 (Wester & Voegtle, 1980) with pyridine-3,5-dicarbonyl dichloride (Chen et al., 2010).
