    • Abstract


      Semi-organic crystal of potassium 4-methyl benzene sulphonate (KOPT) was grown by slow evaporation solution growth technique. Structural parameters of the grown crystal were obtained by single-crystal X-ray diffraction analysis. It reveals that the crystal belongs to monoclinic system and crystallized in noncentrosymmetric space group P2$_1$. The vibrational frequencies of corresponding functional groups in the compound were analysed by Fourier-transform infrared and FT-Raman spectroscopy. ${}^1$H and ${}^{13}$C NMR spectral analyses have been carried out to confirm the molecular structure of the grown crystal. The thermal properties of KOPT were evaluated by thermogravimetric analysis/differential scanning calorimetry measurements. Ultraviolet–Visible spectral studies revealed the cut-off wavelength, transparency and corresponding bandgap (4.5 eV) of KOPT crystal. The dielectric and mechanical characteristics were studied to test the KOPT crystal for nonlinear optical applications.
