A new semi organic non-linear optical single crystal of Trisglycine Zinc Chloride (TGZC) has been grown by slow evaporation solution growth technique. The crystal system and lattice parameters crystals were determined from the single crystal X-ray diffraction analysis. Fourier transform infrared (FTIR) studies confirm the various functional groups present in the grown crystal. The transmittance and absorbance of electromagnetic radiation is studied through UV- Visible spectrum. The mechanical property of grown crystals has been analyzed by Vicker’s microhardness method. The second harmonic generation test has been confirmed by the Kurtz powder technique
