Abstract

Crystallography Physical Sciences Science & Technology
In the title compound, C18H20O4S, the thiophene and benzene rings are oriented at a dihedral angle of 10.83 (11)degrees. The central chain makes dihedral angles of 1.86 (13) and 9.25 (12)degrees with the benzene and thiophene rings, respectively. In the crystal, molecules are linked through weak intermolecular C-H...O interactions. pi-pi interactions are also observed between the benzene rings with a centroid-centroid distance of 3.6832 (12) A. The slippage between the benzene rings is 0.956 A.
