Experimental Crystal data

R factor = 0.041; wR factor = 0.108; data-to-parameter ratio = 18.4. In the title compound, C17H16O3S, the dihedral angle between the 4-methylphenyl ring and the mean plane [r.m.s. deviation = 0.011 (1) Å] of the benzofuran ring system is 71.47 (5). In the crystal, molecules are linked by weak C—H O hydrogen bonds, and by slipped – interactions between the benzo-furan ring systems of neighbouring molecules [centroid– centroid distances = 3.638 (2) and 3.766 (2) Å, interplanar distances = 3.564 (2) and 3.454 (2) Å, and slippages = 0.730 (2) and 1.501 (2) Å], forming a three-dimensional network.
