5-(4-Bromo-phen-yl)-2-(3,4-methyl-ene-dioxy-phen-yl)-3-methyl-sulfanyl-1- benzofuran

Abstract

The title compound, C22H15BrO3S, crystallizes with four mol-ecules in the asymmetric unit. The 4-bromo-phenyl rings are rotated out of the benzofuran planes, with dihedral angles for the four mol-ecules of 20.8 (2), 17.8 (2), 23.5 (4) and 23.9 (4)°. The dihedral angles between the 3,4-methyl-ene-dioxy-phenyl ring and the benzofuran plane are 13.5 (2), 7.1 (2), 18.6 (3) and 14.2 (3)° in the four mol-ecules. The crystal structure is stabilized by weak nonclassical inter-molecular C- H⋯O hydrogen bonds. The crystal structure also exhibits inter-molecular aromatic π-π inter-actions between the benzene and furan rings and between the 4-bromo-phenyl and 3,4-methyl-enedioxy-phenyl rings from mol-ecules 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 mol-ecules.
