The growth and characterization of gallic acid 5-nitrouracilate (GA5NU) single crystals were grown using slow evaporation solution growth technique at room temperature. Single crystal XRD analysis revealed that the grown crystal belongs to monoclinic crystal system. HOMO-LUMO and molecular electrostatic potential (MEP) has been visualized and analyzed. The presence of various functional groups present in the host material was examined using FTIR spectra. Mechanical stability of the grown crystal is validated using Vickers microhardness study and the grown crystal belongs to soft material category. Various hardness parameters like fracture toughness, brittleness index, elastic stiffness constant, tensile strength and other hardness parameters were also calculated. Thermal stability of the grown crystal was also determined. The second harmonic generation (SHG) efficacy of grown crystal was 2.97 times higher than potassium dihydrogen phosphate (KDP), which makes the grown crystal as suitable candidate material for non-linear optical applications.
