In the mol-ecule of the title compound, C28H22F2O4, the benzoyl groups are aligned almost anti-parallel and the fluorobenzene rings form a dihedral angle of 14.12 (7)°. The dihedral angles between the 2,7-dieth-oxy-naphthalene ring system and the benzene rings are 70.00 (4) and 67.28 (4)°. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯F hydrogen bonds, forming layers parallel to the ab plane. The layers are further connected by π-π inter-actions [centroid-centroid distances of 3.6115 (10) Å] into a three-dimensional structure.

The asymmetric unit of the title compound is composed of one host mol-ecule, -4-(1 ,5 -3-aza-1,5(3,9)-dicarbazola-cyclo-octa-phane-3-yl)benzo-nitrile and one di-chloro-methane solvate mol-ecule, CHN·CHCl. The host mol-ecule possesses a planar chirality but crystallizes as a racemate in the space group 2/. It adopts an -configuration, in which two carbazole rings are partially overlapped with a parallel orientation.

The crystal structure of a highly loaded complex of silicalite-1 (SL-1) with eight mol-ecules of -xylene per unit cell has been solved by single-crystal X-ray diffraction. In the crystal, four symmetrical SiO·2CH subunits per unit cell are observed. The -xylene mol-ecules sit at two different positions within the SL-1 channels.
