(E)-1-(5-Chlorothiophen-2-yl)-3-(p-tolyl)prop-2-en-1-one

Abstract

In the title compound, C14H11ClOS, the trans conformation of the C=C double bond in the central enone group is confirmed by the C—C=C—C torsion angle of 178.3 (4)°. The molecule is non-planar as seen by the dihedral angle of 22.6 (2)° between the chlorothiophene and the p-toluene rings. In the crystal, molecules are linked by pairs of C—H...π interactions, forming inversion dimers. There are no other significant intermolecular interactions present.
