چکیده
The asymmetric unit of the title compound, C16H12ClFO2S, contains two independent mol-ecules in which the benzo-furan ring systems are essentially planar, with r.m.s. deviations of 0.007 (1) and 0.013 (1) Å. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into chains extending along the b axis. These chains are further packed into stacks along the c -axis by S⋯O contacts [3.1898 (11) and 3.1361 (11) Å] involving the sulfinyl groups. In both 3-fluoro-phenyl rings, the F atom is disordered over two positions, with site-occupancy factors of 0.921 (2) and 0.079 (2).
