Synthesis, spectral, structural and thermal characterization of NLO active crystal: 2-hydroxyethylammonium-4-nitrobenzoate

An organic crystal, 2-hydroxyethylammonium-4-nitrobenzoate (EANB) was synthesized and single crystals grown by the slow evaporation solution growth method at ambient temperature. The Fourier Infrared (FT-IR) spectral analysis was used to confirm the presence of various functional groups in the grown crystal. The formation of molecular compound and crystal has been confirmed by single crystal X-ray diffraction and NMR spectroscopic techniques. The title crystal crystallizes in monoclinic system, space group P21/c. The thermal stability of crystal was established using Thermogravimetry (TG) and Different Thermal Analysis (DTA) simultaneously. Nonlinear optical (NLO) property in the grown crystal was investigated by the modified Kurtz-Perry powder test.
