(1E,4E)-1,5-Bis(thiophen-3-yl)penta-1,4-dien-3-one

Abstract

The title compound, C13H10OS2, exhibits twists between the central C3O and ethene residues [O—C—C—C torsion angles = −8.4 (3) and 11.8 (3)°], and between the ethene and adjacent thiophenyl residues [C—C—C—C torsion angles = −4.2 (3) and 10.5 (3)°]. As a result, the molecule is non-planar, the dihedral angle formed between the terminal thiophenyl groups being 15.45 (10)°. The presence of C—H...O interactions involving the bifurcated carbonyl O atom leads to supramolecular arrays in the ac plane. These are linked into a three-dimensional architecture by C—H...π interactions involving both thiophenyl residues.
