4-Methylbenzylammonium hydrogen maleate (4MBAHM), a novel organic nonlinear optical single (NLO) crystal has been developed by solvent evaporation method at ambient temperature. The structure of the 4MBAHM crystal has been solved and it reveals monoclinic system and space group P21/c. FT-IR and FT-Raman analyses are carried out to ascertain the functional groups present in the crystal structure. Optical properties are determined by UV–Vis-NIR analysis. 4MBAHM crystal is transparent from 262 to 1100 nm. Proton and carbon environment have been identified using NMR spectroscopy. The NMR spectroscopy reveals the formation of N–H...O, O–H...O and C–H...O bonds between 4-methylbenzylammonium (C8H12N)+ cation and hydrogen maleate (C4H3O4)− anion. The nonlinear optical parameters have been determined using Z-scan study. The third order NLO susceptibility (χ3) value is found to be 2.8975 × 10−5 esu. The closed aperture curve reveal 4MBAHM possess self-defocusing nature and the open aperture curve reveals reverse saturable absorption which find application in the field of night vision devices and optical limiting.
