In the present work, a novel Guanidinium l -glutamate (GLG) optically transparent single crystal has been synthesized and grown by slow solvent evaporation method for the first time is reported. Single crystal X-ray diffraction demonstrates that the GLG crystallizes in non-centrosymmetric monoclinic crystal with P2 1 space group. The different functional groups present in the grown crystal were found by Fourier transform infrared analysis. The optical properties of the grown crystal such as absorbance, laser damage threshold have been studied. The bandgap energy of the crystal was found to be 4.66 eV. Thermal properties of GLG crystalline samples were analyzed using Thermogravimetry/Differential Thermal Analysis. Further, the material is characterized by Hirshfeld surface analysis to analyze and interrupt the intermolecular interactions of GLG. Scanning Electron Microscope (SEM) studies were carried out to study the surface morphology of the grown crystal. By using Kurtz-Perry powder technique second harmonic generation and particle size dependency was carried out for the title compound.
