The grown crystals belong to the <em>monoclinic</em> crystal system with space group <em>P2<sub>1</sub>/c</em>. Good crystalline nature of grown BISA crystal was confirmed by PXRD. The FTIR spectrum analysis affirms the presence of functional groups in BISA crystal. From the UV‒Vis-Absorption spectrum, the lower cut-off wavelength (356 nm) and its energy band gap and linear refractive index were calculated. Luminescence spectrum was recorded to explore the emission peak at 426 nm. The mechanical strength of BISA crystal was determined by Vickers microhardness tester and mechanical parameters like C<sub>11</sub>, H<sub>k</sub>, K<sub>c</sub>, and B<sub>i</sub> were calculated for the first time. Dielectric properties of grown crystals were systematically investigated for different temperatures. Further, electronic polarizability (α) were calculated using Penn analysis and Clausius‒Mossotti equation. Z‒scan measurement was taken to explore the third-order NLO properties of BISA crystal. For the first attempt, the BISA crystals were tested against five human pathogenic bacterial, i.e. <em>Bacillus cereus, Staphylococcus aureus, Shigella flexneri, Vibrio cholerae, </em>and<em> Klebsiella pneumoniae</em>. Existing results established that Benzimidazolium salicylate crystals might find useful applications in nonlinear optics and antimicrobial field.</p>}, number={3}, journal={Physics and Chemistry of Solid State}, author={Sakthy Priya , S. and Balakrishnan, K. and Lakshmanan, A. and Surendran, P. and Rameshkumar, P. and Kannan, Karthik and Geetha, P. and Hegde, Tejaswi Ashok and Vinitha, G.}, year={2020}, month={Sep.}, pages={377–389} }
