5-Chloro-3-ethylsulfinyl-2-(3-fluorophenyl)-1-benzofuran

Abstract

The asymmetric unit of the title compound, C16H12ClFO2S, contains two independent molecules in which the benzofuran ring systems are essentially planar, with r.m.s. deviations of 0.007 (1) and 0.013 (1) Å. In the crystal, molecules 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-fluorophenyl rings, the F atom is disordered over two positions, with site-occupancy factors of 0.921 (2) and 0.079 (2).
