(E)-2-(3-Oxo-3-phenylprop-1-enyl)thiophene-3-carbaldehyde

Abstract

The title compound, C14H10O2S, crystallizes with two independent molecules (A and B) in the asymmetric unit. They have very similar conformations with the thiophene ring having an envelope conformation in both molecules. In molecule A, the benzene and thiophene rings makes a dihedral angle of 11.01 (9)°. The corresponding angle in molecule B is 9.58 (9)°. In the crystal, molecules are linked via pairs of C—H...O hydrogen bonds, forming dimers with an R 2 2(18)set-graph motif. The dimers are linked via C—H...O hydrogen bonds, forming slabs lying parallel to (100).
