2-Amino-5-chloropyridinium 5-sulfosalicylate (2A5CP5S) material was synthesized, and a single crystal was grown by slow evaporation solution technique (SEST). The lattice parameters of the grown crystal were confirmed by the single-crystal X-ray diffraction (SXRD) analysis. It was a triclinic crystal system with a centrosymmetric P-1 space group. The various crystal planes were determined using powder X-ray diffraction (PXRD) analysis. The functional groups of the 2A5CP5S were identified by FTIR spectrum analysis. The dislocation density of the crystal was analyzed by chemical etching analysis. The thermal behavior of the 2A5CP5S crystal was determined by thermogravimetric and differential thermal analysis. The optical homogeneity of the crystal (thickness = 1 mm) was characterized by a birefringence study using a diode laser (532 nm). The photoconductivity was tested on a polished sample with an exposed area of 25 mm 2 . The optical transmittance of the grown crystal was found using UV–Vis NIR spectroscopy, it is 78% and the bandgap energy was found to be 3.35 eV. The z-scan technique was carried out using a He–Ne laser (632.8 nm) to analyze the nonlinear optical (NLO) properties.
