Single crystals of Triglycine barium dichloride dihydrate were grown by slow evaporation technique. The unit cell dimensions and space group of the grown crystals were confirmed by single crystal X-ray diffraction. The functional groups present in the structure of the grown crystal are identified by using FTIR spectral analysis. The microhardness study shows that the Vickers hardness number of the crystal increases with the increase in applied load. Dielectric constant and dielectric loss measurements were carried out for different temperatures and frequencies.
