A potential crystal for nonlinear optical application and monomer namely 1-(2,4-dichloro-phenyl-2yl)-3-(4-hydroxyphenyl)prop-2-en-1-one (DHPP) was synthesized and grown by slow evaporation technique. The functional groups present in the compound were identified by FTIR spectrum. The optical cut-off wavelength and structural characteristics were analyzed using UV-Vis-NIR spectra and single crystal x-ray diffractometer. The crystal belongs to non centrosymmetric orthorhombic system with space group Pna21 with cell parameters a= 18.015(3) Å, b= 18.218(3)Å, c= 4.1029(6) Å, Z=4 and V= 1346.56Å3. Thermal studies show that the crystal is stable up to 250 0C implying good processability.
