The mechanical studies, using microhardness methods, have also been carried out. The compound is characterised using UV, FT-IR and NMR spectral studies. Furthermore, the thermal stability of the crystal is established by TG/DTA. The nonlinear optical studies (SHG) of the crystal have been determined using the Kurtz and Perry powder technique and the activity observed is 2.5 times greater than that of KDP.</p> ER -
