Abstract
In the title compound, C21H13BrO4S·C6H6, the O atom and the phenyl group of the phenylsulfinyl substituent are located on opposite sides of the mean plane of the 5,6-methylenedioxybenzofuran fragment; the phenyl ring is almost perpendicular to this plane [83.66 (6)°]. The 4-bromophenyl ring is rotated slightly out of the 5,6-methylenedioxybenzofuran plane, making a dihedral angle of 2.9 (1)°. The crystal structure is stabilized by intermolecular C—H⋯O hydrogen bonds and intermolecular C—H⋯π interactions. The crystal structure also exhibits π–π interactions between the benzene ring and the 4-bromophenyl ring of an adjacent molecule [centroid–centroid distance = 3.586 (3) Å].
