5-Bromo-2-methyl-3-(4-methyl-phenyl-sulfin-yl)-1-benzofuran.

ABSTRACT: In the title compound, C(16)H(13)BrO(2)S, the 4-methyl-phenyl ring makes a dihedral angle of 87.83?(6)° with the mean plane [mean deviation = 0.007?(1)?Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds and Br?O contacts [3.099?(2)?Å]. The crystal structure also exhibits ?-? inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.637?(2)?Å, inter-planar distance = 3.317?(2)?Å and slippage = 1.492?(2)?Å].
