✦ Synopsis

1-ð2 0 -ThiophenÞ-3-ð2,3,5-trichlorophenylÞ-2-propen-1-one (TTCP) was synthesized by Claisen-Schmidt condensation reaction. FT-IR spectra were recorded to identify the functional groups present in the compound. The NLO test carried out on the sample using Z-scan technique confirms the existence of nonlinearity in the third harmonic generation. Further, the compound is characterized by UV-visible spectral studies for the optical transmission. Finally, the structure of the product obtained was confirmed by the X-ray diffraction studies. The compound crystallizes in the monoclinic space group P2 1 =c with a ¼ 16:6170ð6Þ Å, b ¼ 7:6180ð5Þ Å, c ¼ 10:9280ð11Þ Å and b ¼ 104:635ð3Þ1. The thiophene ring shows planar conformation and is affected by p conjugation. The unsaturated keto group is in þ syn-periplanar conformation. The molecule exhibits both inter and intramolecular hydrogen bonds of the type C-H Á Á Á O and C-H Á Á Á Cl which can account for the stability of the molecule.
