چکیده
The title compound, C(15)H(14)O(3)S, has two symmetry-independent mol-ecules in the asymmetric unit with almost identical geometry. The dihedral angle between the benzene and thio-phene rings is 1.61 (11)° in one mol-ecule and 7.21 (11)° in the other. In both mol-ecules, C-H⋯O hydrogen bonds generate rings of graph-set motif S(5). The crystal structure is stabilized by C-H⋯O hydrogen bonds, C-H⋯π inter-actions and π-π inter-actions involving the benzene and thio-phene rings, with centroid-centroid distances of 3.5249 (13) and 3.6057 (13) Å.
