| Summary: | The title compound, C10H12O2S, crystallizes with four molecules in the asymmetric unit. The main conformational difference between these molecules is the orientation of the acetyl groups with respect to the ring. Whereas one acetyl group is only slightly twisted with respect to the thiophene ring [C—C—C—O torsion angles = 165.7 (4), −164.6 (4), 164.3 (4) and −163.6 (4)°], the other acetyl group is markly twisted out of the ring plane [C—C—C—O torsion angles = −61.2 (6), 61.3 (7), −59.7 (7) and 59.9 (6)°]. In the crystal, molecules are linked by weak C—H...O interactions into infinite chains along the c axis.
