(2E)-3-(3,4-dimethoxyphenyl)-1-(2,5-dimethylthiophen-3-yl)prop-2-en-1-one

Abstract

The mol-ecule of the title compound, C17H18O 3S, is essentially planar: the phenyl and thio-phene rings form a dihedral angle of 2.79 (10)° and they are inclined to the central propenone unit by 6.20 (15) and 4.78 (15)°, respectively. In the crystal, mol-ecules are connected into dimers via pairs of C - H⋯O inter-actions, generating R 22(14) motifs. π-π stacking inter-actions between the thio-phene rings also occur, with a centroid-centroid distance of 3.8062 (12) Å.
