title: Growth and characterization of 2-amino-4-picolinium 4-aminobenzoate single crystals.
abstract: The organic material of 2-amino-4-picolinium 4-aminobenzoate (C(6)H(9)N(2)(+).C(7)H(6)NO(2)(-)) was synthesized and grown as single crystals at room temperature by slow evaporation solution growth technique in the constant temperature bath (+/-0.01 degrees C) using ethanol as solvent. The grown crystals were characterized by XRD and FT-IR spectral analyses. The melting point, density, UV-visible spectral studies were carried out for the grown crystals. The theoretical factor group analysis predicts 372 internal modes of vibration and optical modes in the grown title compound. The second harmonic generation (SHG) output of 2-amino-4-picolinium 4-aminobenzoate was recorded by Kurtz-Perry powder technique and it is found to be 355 mV at a given pulse energy of 1.45 mJ/s and for urea the SHG output was 525 mV. The dielectric behaviour of 2-amino-4-picolinium 4-aminobenzoate was investigated with different frequencies and temperatures.
