Crystal Growth, Spectral and Optical Studies of 2-Aminoanilinium Benzoate Single Crystal

The proton transfer or H-bonded complex of 2-aminoanilinium benzoate (OPDB) was synthesized from O-phenylenediamine as donor and benzoic acid as acceptor. OPDB crystals were grown by solution growth technique. The cell parameters and crystalline perfection of the grown crystal were studied by single crystal and powder X-ray diffraction analyses. The title compound was classified into orthorhombic crystal system with non-centrosymmetric P212121 space group. FTIR spectral analysis revealed the existence of functional groups and their corresponding vibrational modes have been assigned. The optical transmission properties of the crystal were studied by UV–Vis spectral analysis. Laser induced damage threshold of the grown crystal was estimated using Nd:YAG laser source. The second harmonic generation efficiency of the grown crystal was studied by Kurtz-Perry test.
