A new nonlinear chalcone organic crystal 1,3-bis(2-methylbenzal)acetone (TAZn) doped with zinc chloride has been synthesized and single crystal has been grown by slow evaporation method. TAZn single crystal of has been subjected to X-ray Diffraction (XRD) analysis to estimate the lattice parameters and the space group. TAZn was found to be crystallizes in the orthorhombic system, with space group Pbca having lattice parameters: a=13.7471(4)Å, b=8.6498(8)Å, c=25.5629(16)Å, α=ï¢=ï¬=90°. The qualitative analysis of TAZn crystal has been carried out using Fourier Transform Infrared (FTIR) and Raman spectra measurements. The presence of zinc in TAZn crystals was also confirmed by elemental analysis. The Kurtz powder technique was adopted preliminarily to check the optical nonlinearity of the crystal. SHG efficiency of TAZn is found to be 2.5 times that of KDP.
