An organic Diethanolaminium 4-Nitrobenzoate (DANB) crystal was grown at 30 ℃ using slow evaporation. A positive temperature gradient was observed from the solubility data. The Single crystal XRD confirmed the formation of the title compound. The various functional groups and the carbon and hydrogen present in different chemical environments were identified by FTIR and NMR spectroscopy respectively. The Hirshfeld Surfaces show the existence of π–π stacking and quantify the different intermolecular contacts. The variation in the optical properties of the grown crystal upon loading the shock waves has been studied through the UV–Vis-NIR analysis. The Refractive index of the grown crystal increased with the Mach number. The Hardness studies suggest that the crystal belongs to the soft material category. The hardness parameters such as the Stiffness constant and yield strength increase with the applied load. The third-order nonlinear susceptibility was determined as 5.49 × 10 –8 esu from Z-Scan studies. The self-defocusing nature and reverse saturable absorption behaviour of DANB are inferred from the closed and open aperture curves.
