(E)-3-Dimethyl-amino-1-(2,5-dimethyl-thio-phen-3-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C(11)H(15)NOS, the 3-(dimethyl-amino)-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 thio-phene ring. In the crystal, mol-ecules 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?? inter-actions. The two methyl groups, attached to the thio-phene 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.

In the title compound, C(11)H(15)NOS, the 3-(dimethyl-amino)-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 thio-phene ring. In the crystal, mol-ecules 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 inter-actions. The two methyl groups, attached to the thio-phene ring and the  ...[more]
