5-(4-Bromophenyl)-2-(3,4-methylenedioxyphenyl)-3-methylsulfanyl-1-benzofuran

The title compound, C22H15BrO3S, crystallizes with four molecules in the asymmetric unit. The 4-bromophenyl rings are rotated out of the benzofuran planes, with dihedral angles for the four molecules of 20.8 (2), 17.8 (2), 23.5 (4) and 23.9 (4)°. The dihedral angles between the 3,4-methylenedioxyphenyl ring and the benzofuran plane are 13.5 (2), 7.1 (2), 18.6 (3) and 14.2 (3)° in the four molecules. The crystal structure is stabilized by weak nonclassical intermolecular C—H...O hydrogen bonds. The crystal structure also exhibits intermolecular aromatic π–π interactions between the benzene and furan rings and between the 4-bromophenyl and 3,4-methylenedioxyphenyl rings from molecules of the same type; the centroid–centroid distances are 3.92 (1) and 3.79 (1), 3.91 (1), 3.77 (1) and 3.77 (1), and 3.79 (1) and 3.75 (1)Å in the four molecules.
