ABSTRACT. Single crystals of 2,5-dimethylanilinium dihydrogen phosphate (2,5-DADP) were grown by slow evaporation solution growth technique in room temperature. The crystalline nature of the grown crystal was confirmed from the single crystal X-ray data. The grown crystal 2,5-DADP was found to crystallize in orthorhombic system with non-centrosymmetric space group P212121. Optical transparency of the grown crystal was studied by UV–Vis-NIR spectroscopy. The dielectric loss and dielectric constant measurement as a frequency and temperature were measured on 2,5-DADP single crystal. Microhardness measurements revealed that 2,5-DADP belongs to a soft material category .The second harmonic generation of the crystal was confirmed and the efficiency was measured using Kurtz Perry powder method.

Keywords: Crystal growth, X-ray diffraction, Optical properties, Mechanical properties, NLO crystals.
