title: 20,23,26,29,32,35,38,41-Octa-oxa-5,9,13-triaza-penta-cyclo-[15.14.10.1.1.1]tetra-tetra-conta-1,3(42),7,9,11(44),15(43),16,18,30-nona-ene-6,12-dione acetone mono-solvate.
abstract: In the crystal structure of the title compound, C(33)H(39)N(3)O(10)·C(3)H(6)O, the acetone mol-ecule 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 inter-actions link neighbouring cryptands. The dihedral angles between the pyridine ring and the benzene rings are 86.47 (17) and 85.53 (13)°.
