crystal XRD analysis and the crystals belong to orthorhombic system with noncentrosymmetric space group P212121, resulting in highly translucent and nonlinear optical properties. The direct and indirect bandgap energies were evaluated by utilizing Kubelka–Munk algorithm. The efficiency of IBMB in terms of nonlinear optical (NLO) activity was verified and the hydrazone displayed higher NLO activity compared
