A new semi-organic nonlinear optical crystal of Glycine Magnesium Chloride (GMC) has been grown by slow evaporation solution growth technique. The crystal system and lattice parameters 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 UVVisible spectrum. The mechanical property of grown crystals has been analyzed by Vicker’s microhardness method. The thermal behavior of the grown crystals has been investigated by DTA and TGA analysis. The second harmonic generation test has been confirmed by the Kurtz powder test.
