Abstract
Three chlorinated theinyl chalcone derivatives, namely (E)-1-(5-chlorothiophen-2-yl)-3-(4-(methylthio)phenyl)prop-2-en-1-one (I), (E)-1-(5-chlorothiophen-2-yl)-3-(4-(dimethylamino)phenyl)prop-2-en-1-one (II) and (E)-1-(5-chlorothiophen-2-yl)-3-(2,3-dihydrobenzofuran-5-yl)prop-2-en-1-one (III), were synthesized and their crystal structures were determined by single-crystal X-ray diffraction analysis. Compounds I, II and III crystallize in the monoclinic space groups P 21/c (centrosymmetric), P 21/n (centrosymmetric) and Pc (non-centrosymmetric), respectively. In all three compounds, the molecules are in a relatively planar conformation and adopt a trans configuration with respect to the C=C double bond. The crystal packings are stabilized by weak hydrogen-bonds, π · · · π, C–H · · · π and C–Cl · · · π interactions. The intermolecular contacts and lattice energies were further analyzed by Hirshfeld surface analysis. The third-order nonlinear optical properties of these chalcone derivatives were investigated using the single beam Z-scan technique with a 5 mW continuous wave diode laser operating at 635 nm, where compound I showed the highest potential for optical application with its exclusive nonlinear refractive index and nonlinear susceptibility.

Abstract
In the title compound, C15H10Cl2O, the dihedral angle between the aromatic rings is 5.59 (15)° and the C—C=C—C torsion angle is 177.5 (3)°. In the crystal, molecules are linkedviapairs of C—H...O hydrogen bonds, forming inversion dimers withR22(10) ring motifs.
