A semi-organic single crystal named tris(cyclohexylammonium) tris(o-chlorobenzoate) dihydrate (TCTCDH) had been successfully grown applying slow evaporation procedure. The developed crystal was involved for various characterization techniques. The structural property of the sample had been analyzed employing powder XRD study. The FT-IR spectral study was applied to confirm the existence of functional groups in the title compound. The optical property of the grown material has been explored using UV-visible NIR spectral study. The dielectric constant and dielectric loss were calculated to analyze the electrical property of the titular crystal. The third-order nonlinear susceptibility of the grown material was studied employing Z-scan technique using semiconductor laser at 532 nm. The thermal behavior of TCTCDH compound was ascertained using thermo-gravimetric analysis (TGA) and differential scanning calorimetry (DSC) analysis. The Vicker’s hardness study was employed to determine the mechanical stability of TCTCDH compound. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
