L-Histinium 5 Sulfo Salicylate , an organic NLO crystal was grown for the first time by slow evaporation solution technique. Single crystal X ray diffraction analysis reveals that H5S belongs to monoclinic crystal system with non-centro symmetricspace group P21. The determined parameters are a=9.5707(17)A 0 , b= 19.038(4)A 0 , c= 8.315(2)A 0 ,β= 90.711(14) and V= 1514.8(6)A 3. FT-IR and FT Raman studies were carried out to identify the functional groups prevent in H5S. Optical absorption study showed a UV cut off wavelength of 304 nm. The mechanical properties of the grown crystal has been analyzed by Vicker micro hardness method. The second harmonic generation was confirmed for LH5SS.
