Single crystals of L-lysine L-tartaric acid (LLLT) were grown by solution method using double distilled water as the solvent. The grown crystals LLLT were subjected to characterization studies like XRD studies, mechanical studies, optical studies and SHG studies. From XRD studies, it is ascertained that LLLT crystal crystallizes in monoclinic structure. The grown crystal has high transmittance in the visible region and it has high optical band gap. The mechanical parameters like hardness, work hardening coefficient, yield strength, stiffness constant, brittleness index, corrected hardness and resistance pressure of LLLT crystal have been evaluated by using Vickers microhardness method. The relative SHG efficiency of LLLT crystal has been determined by Kurtz-Perry powder technique.
