Crystal structure of (6E,20E)-3,24-difluoro-13,14,28,29-tetrahydro-5H,22H-tetrabenzo[e,j,p,u][1,4,12,15]tetraoxacyclodocosine-5,22-dione

Abstract

The conformation of the title compound, C34H26F2O6, is cone-shaped, partially determined by intramolecular C—H...O short contacts. The benzene rings at the top of the cone are inclined to one another by 73.10 (7)°, while the benzene rings at the bottom of the cone are inclined to one another by 35.49 (8)°. In the crystal, molecules are linked by C—H...O and C—H...F hydrogen bonds, forming a three-dimensional supramolecular structure. There are also C—H...π contacts present within the framework structure.
