Using slow evaporation solution growth technique, single crystal of Lithium para nitro phenolate (LPNP) has been grown from the equimolar mixture of para-nitro phenol and lithium hydroxide mono hydrate. Structural analyses were carried out by powder x-ray diffratcion method, FTIR and NMR methods to confirm the grown crystals. Thermal stability of the grown crystal is studied by Thermogravimetric (TG) and Differential Thermal analyses (DTA). The mechanical behavior of the grown crystal has been studied by Vicker's micro hardness method. UV-Vis spectral analysis has been carried out to find the transparency of the grown crystal. Nonlinear optical property has been confirmed by Kurtz powder technique. The observed properties have confirmed that the grown crystal is suitable for nonlinear optical applications..
