title: Crystal structure, thermal and spectral studies and growth of nonlinear optical L-lysinium fluoride crystal.
abstract: In current study properties of L-lysinium fluoride (L-Lys⋅HF) are determined by X-ray diffraction, infrared and Raman spectroscopy, SHG and by UV-vis transmittance spectrum measurement. L-Lys⋅HF (C6H15FN2O2), crystallizes in a monoclinic system with space group P21, a=5.464(1)Å, b=7.4717(15)Å, c=10.252(2)Å, α=γ=90°, β=99.17(3)°, Z=2, ρc=1.336Mg/m(3), ρm=1.335(2)Mg/m(3). By means of evaporation method high quality L-Lys⋅HF single crystals are grown from aqueous solutions. L-Lys⋅HF crystal is transparent in the wavelength region 240-1100nm and it exhibits powder SHG efficiency 0.65 times that of potassium dihydrogen phosphate (KDP).
