Crystal structure of 5-chloro-2,4,6-trimethyl-3-(4-methylphenylsulfinyl)-1-benzofuran

Abstract

In the title compound, C18H17ClO2S, the dihedral angle between the planes of the benzofuran ring [r.m.s. deviation = 0.013 (1) Å] and the 4-methylphenyl ring is 87.37 (5)°. In the crystal, molecules are linked by C—H...O hydrogen bonds and π–π interactions between the furan and benzene rings of neighbouring molecules [centroid–centroid distance = 3.525 (2) Å]. In addition, an S...S [3.6584 (9) Å] contact is observed.
