Crystal structure and Hirshfeld surface analysis of (2E)-3-(3-chlorophenyl)-1-(3,4-dimethoxyphenyl)prop-2-en-1-one

Abstract

In title compound, C17H15ClO3, the dihedral angle between the benzene and chlorophenyl rings is 18.46 (7)°. In the crystal, molecules are linked by C—H...O hydrogen contacts, enclosing an R22(14) ring motif, and by a further C—H...O hydrogen contact, forming a two-dimensional supramolecular structure extending along the direction parallel to the ac plane. Hirshfeld surface analysis shows that van der Waals interactions constitute the major contribution to the intermolecular interactions, with H...H contacts accounting for 36.2% of the surface.
