3-Ethylsulfinyl-2-(3-fluorophenyl)-5,6-methylenedioxy-1-benzofuran

Abstract

In the title compound, C17H13FO4S, the 3-fluorophenyl ring makes a dihedral angle of 6.14 (5)° with the mean plane [r.m.s. deviation = 0.008 (1) Å] of the benzofuran fragment. In the crystal, molecules are linked by weak C—H...F, C—H...O and C—H...π interactions, forming a three--dimensional network. The crystal structure also exhibits slipped π–π interactions between the 3-fluorophenyl rings of neighbouring molecules [centroid–centroid distance = 3.769 (2) Å and slippage = 1.684 (2) Å].
