Fig. 5: Chemical and X-ray crystal structures of 5, 6, 7 and 8.
From: Mechanochemical transformation of planar polyarenes to curved fused-ring systems
The structures for 5 and 6 are found to be disordered at the halogen atoms due to cocrystallization of compounds carrying bromide (shown with a green colour) and chloride (shown with a brown colour) substituents.
