A new third order nonlinear optical single crystal of 2-phenylbenzimidazolium-p-toulenesulphonate (PBITS) was grown by the solvent evaporation technique using methanol as a solvent. The single crystal XRD analysis reveals that crystals belong to the triclinic system. An NMR and FTIR study confirms the formation and vibrational analysis present in the compound. UV-Vis absorption studies were also carried out for the crystal. Nonlinear refractive index (n₂), absorption coefficient (β) and third order nonlinear optical susceptibility (χ⁽³⁾) of the crystals were evaluated by Z-Scan studies.
