In the title here compound, C11H15NOS, the 3-(dimethylamino)prop-2-en-1-one unit is approximately planar [maximum deviation = 0.0975 (14) Å] and its mean plane of seven non-H atoms makes a dihedral angle of 6.96 (10)° with the thiophene ring.In the crystal, molecules are linked by pairs of C—H.O hydrogen bonds alarecre.com into inversion dimers with R22(14) ring motifs.

The dimers are stacked along the c axis through C—H.π interactions.The two methyl groups, attached to the thiophene ring and the amino N atom, are each disordered over two orientations, with site-occupancy ratios of 0.59 (4):0.41 (4) and 0.

74 (4):0.26 (4), respectively.
