5,6-dichloro-2-(2-fluorophenyl)isoindoline-1,3-dione

Abstract

The crystal structure of the title compound, C14H6Cl2FNO2, exhibits C-H center dot center dot center dot pi and pi-pi interactions, which generate C(3) chains in the [100] direction. The pi-pi interaction occurs between the aromatic rings of isoindoline units, with a centroid-centroid distance of 3.672 angstrom and an interplanar separation of 3.528 angstrom. The isoindoline unit is planar and inclined at an angle of 58.63 (18)degrees to the substituent benzene ring. The F atom is disordered over two positions, with refined occupancies of 0.669 (3) and 0.331 (3).
