Organic nonlinear optical crystal of 2-aminopyridinium p-Aminobenzoate have been grown by slowevaporation solution growth method at room temperature using ethanol:water as mixed solvent. From the single crystalX-ray diffraction study, it is confirmed that PA2A crystal belongs to orthorhombic crystal system with space group P.From the powder XRD pattern, the various planes of reflections and crystal perfections were identified. The presence offunctional groups in the synthesized compound was identified by FTIR spectral analysis. The cut-off wavelength andtransmittance were determined by UV-Visible spectra. From the Photoluminescence spectra, high intensity violetemission peak observed at 360 nm with excited at 345 nm. The Kurtz-Perry powder second harmonic generationtechnique confirms the nonlinear optical property of the grown crystal. The SHG relative efficiency of PA2A crystal hasbeen found 2.2 times higher than that of KDP.
