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.
