Single crystals of GNaNO 3  were grown by the slow evaporation technique. The crystallinity of the grown crystals was confirmed by single-crystal X-ray diffraction. The GSN crystal belongs to space group Cc in the monoclinic system. Using an FTIR spectrophotometer, different functional groups were qualitatively identified. The optical absorption spectra and optical energy band gap of GSN crystal were recorded using an UV–Vis–NIR spectroscopy. The optical transmission spectra revealed very high transmittance throughout the visible region. The TG–DTG trace demonstrates that the grown crystal is extremely stable. The grown crystals' second harmonic generation was confirmed using the Kurtz and Perry powder SHG method and KDP. The LASER threshold damage of GNaNO 3  is found to be good. The GNaNO 3  possesses antibacterial activity against staphylococcus epidermis is confirmed with the agar well diffusion method. The crystal GNaNO 3 shows good antioxidant and anticancer activity. GSN crystal is an excellent candidate for the fabrication of NLO devices and pharmaceutical applications due to their properties.
