Synthesis growth and characterization of l-valine nickel (II) chloride: A novel semiorganic nonlinear optical crystal

A new semi organic nonlinear optical crystal, l -valine nickel chloride has been synthesized and good optical quality single crystals were grown by slow evaporation technique. The growth conditions of the crystals are studied and the grown crystals are confirmed by powder X-ray diffraction studies. The grown crystal was characterized by using powdered XRD, FT-IR, UV–Vis–NIR, EDAX, and TG–DTA. The crystalline nature and its various planes of reflections were observed by the powder XRD. The presence of various functional groups was confirmed by FT-IR spectroscopic technique. The UV–Vis–NIR spectrum indicates that the crystal has very good absorption in the entire visible and near IR region spectrum suggesting the suitability of the material for NLO applications. The decomposition temperatures and mass loss have been estimated from the thermogravimetric analysis.
