Abstract
ABSTRACTWell-developed transparent single crystals of bis-glycine lithium bromide were grown by the slow evaporation method. The grown crystals were characterized by powder X-ray diffraction analysis, Fourier transform infrared spectroscopy, thermogravimetric analysis (TGA), differential thermal analysis and differential scanning calorimetry analyses. UV–VIS–NIR spectrum shows excellent transmission in the UV, visible and NIR regions. Mechanical properties of the grown crystals were studied using the Vickers microhardness tester. Third-order nonlinear optical properties were studied in detail by the Z-scan technique with He–Ne laser radiation of wavelength 632.8 nm and the corresponding nonlinear refractive index, absorption coefficient and optical susceptibility were calculated.
Highlights
Complexes of glycine have recently attracted attraction due to their potential applications in ferroelectricity [1,2,3], dielectric properties [4] and nonlinear optical properties [5,6,7,8,9,10,11,12,13,14,15,16,17]
As part of continuation of our study, we report here the growth of glycine lithium bromide from aqueous solution by the solvent evaporation method

Summary
Complexes of glycine have recently attracted attraction due to their potential applications in ferroelectricity [1,2,3], dielectric properties [4] and nonlinear optical properties [5,6,7,8,9,10,11,12,13,14,15,16,17]. Six complexes of glycine with inorganic lithium salts have been published. We have isolated a new compound glycine lithium bromide and its single crystal structure was described [21]. Single crystal X-ray structure solution analysis reveals that the hydrated form of glycine lithium bromide crystallizes in the monoclinic system, with space group P21/c. As part of continuation of our study, we report here the growth of glycine lithium bromide from aqueous solution by the solvent evaporation method. Third-order nonlinear optical properties were studied in detail by the Z-scan technique
