Growth and characterization studies of an efficient semiorganic NLO single crystal: 2-Amino 5-nitropyridinium sulfamate (2A5NPS) by assembled temperature reduction (ATR) method

• It is new crystalline structure.
• 2-Amino 5-nitropyridinium sulfamate is potential NLO candidate.
• It has low reflectance and extinction coefficient, so we can use for device fabrication.

Semiorganic crystals of 2-amino 5-nitropyridinium sulfamate (2A5NPS) were grown by slow evaporation and slow cooling method. A asymmetric grown crystal was subjected to single crystal X-ray diffraction and X-ray powder diffraction by using Bruker Kappa APEX11 CCD diffractometer and Philips analytical powder X-ray diffractometer respectively. Vibrational frequency of 1:1 equimolar ratio single crystals of 2-amino 5-nitropyridinium sulfamate (2A5NPS) was measured using FTIR and thermal stability of the grown crystal of 2-amino 5-nitropyridinium sulfamate (2A5NPS) was also measured. Optical properties of the grown crystal and NLO test were also carried out.
