Brucinium hydrogen (S) malate pentahydrate (BH(S)M), an organic compound, has been synthesized, and BH(S)M single crystals were grown from an ethanol/water solution by slow evaporation of the solvent at room temperature up to dimensions of 15 × 4 × 2 mm3. Single-crystal X-ray diffraction study shows that they belong to a triclinic system (a = 9.342 Å, b = 9.510 Å, c = 16.874 Å, a = 76.61°, b = 89.14°, and g = 81.79°) in a non-centrosymmetric space group P1. Fourier transform infrared (FTIR) spectroscopic study was performed to identify different modes of functional groups present in the compound. The UV-Vis-NIR transmission spectrum has been recorded in a range of 200–1100 nm. It exhibits maximum transparency (87%) in the 425–650 nm range, suggesting the suitability of the title compound for optical applications. The thermal stability of the compound has been determined by TG-DTA curves. Microhardness tests have been performed on the crystal under study, and the Vickers hardness number has been calculated. The work hardening coefficient is found to be 4.2, which suggests that the crystal belongs to the family of soft materials. The SHG efficiency of the crystal was evaluated by the Kurtz powder technique using a Nd:YAG pulsed laser.
