Sodium thiourea nitrate (STN) a semi organic optical crystal was grown by slow evaporation technique at room temperature. The cell parameter value and crystal structure was determined Single crystal Xray diffraction study. Presence functional group was identified FTIR study. The cut-off wavelength was determined UV-visible transmission spectrum study. The mechanical strength was analysis using Vicker’s microhardness test.
