2-(2-Fluorophenyl)-5-iodo-7-methyl-3-methylsulfinyl-1-benzofuran

Abstract

In the title compound, C16H12FIO2S, the dihedral angle between the plane of the benzofuran ring system (r.m.s. deviation = 0.023 Å) and that of the 2-fluorophenyl ring is 39.78 (7)°. In the crystal, molecules are linkedviapairs of I...π contacts [3.812 (2) Å] and a π–π interaction between the benzene rings of neighbouring molecules [centroid–centroid distance = 3.821 (2) Å] into inversion dimers. These dimers are further linked by π–π interactions between the furan and benzene rings of neighbouring molecules [centroid–centroid distance = 3.668 (2) Å]. The molecules stack along thea-axis direction. In addition, C—H...O hydrogen bonds are observed between inversion-related dimers.
