| Abstract: | Single crystal growth, spectroscopic, relative second harmonic generation (SHG) efficiency and thermal analysis of 2-aminopyridinium picrate (2APP) is reported for the first time. Crystals were grown by the slow evaporation solution technique using methanol as a solvent. The crystal system and lattice parameters were confirmed by single crystal and powder XRD analyses. FT-IR and FT-Raman spectroscopic studies were carried out to identify the functional groups and vibrational modes present in the grown crystal. Crystalline perfection of the grown crystal was assessed by high-resolution XRD and the results reveal that the crystal is reasonably good. SHG efficiency was measured using Kurtz powder technique. Thermogravimetric (TG) and differential thermal analysis (DTA) studies were carried out and show that the grown single crystal is stable up to 223 °C. |
