Abstract

Organic material of 2-amino-3-nitropyridine (ANP) single crystal was grown by slow evaporation technique at ambient temperature using dimethylsulfoxide (DMSO) as a solvent. The grown crystals were subjected to various characterization studies. The powder XRD analysis shows the crystal phases and crystallinity were identified. Functional groups of the grown material were confirmed by FT-IR vibrational spectrum. The UV- Visible absorption spectrum has been recorded and it shows that cut - off wavelength at 524 nm. Dielectric measurements were carried different temperatures at 313 K to 373 K. From the dielectric studies reveals the both dielectric constant and dielectric loss were increases in lower frequency and decreases in higher frequencies. Thermal behavior of ANP compound was studied using thermo gravimetric (TG) and differential thermal analyses (DTA) it is thermally stable up to 383 K. The second harmonic generation (SHG) behavior of ANP was evaluated by Kurtz-Perry powder technique.
