Crystal structure and Hirshfeld surface analysis of (2E)-3-(3-chloro-phen-yl)-1-(3,4-di-meth-oxy-phen-yl)prop-2-en-1-one

In title compound, C(17)H(15)ClO(3), the dihedral angle between the benzene and chloro-phenyl rings is 18.46 (7)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen contacts, enclosing an R(2)(2)(14) ring motif, and by a further C-H⋯O hydrogen contact, forming a two-dimensional supra-molecular structure extending along the direction parallel to the ac plane. Hirshfeld surface analysis shows that van der Waals inter-actions constitute the major contribution to the inter-molecular inter-actions, with H⋯H contacts accounting for 36.2% of the surface.
