Abstract

In the title 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 into inversion dimers with R 2 2(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.
