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.
