Abstract

A metal organic non-linear optical crystal of 2-Amino pyridine potassium thiocynate glycine (2-APKSNG) was grown at room temperature by slow evaporation technique. Crystalline nature and lattice parameters have been studied by powder and single crystal X-ray diffraction analysis. FTIR spectral study of the grown crystal confirms the chemical composition and their corresponding functional groups. UV–visible NIR spectral study confirms the transmission band from 200 nm to 900 nm with lower cutoff wave length at 250 nm. Thermal and dielectric studies of as grown crystals were studied and discussed. The SHG efficiency of the grown crystal was confirmed by the Kurtz powder technique..
