Growth,crystal perfection,optical and electrical properties of organic crystal: Brucinium 5-sulfosalicylate trihydrate

Single crystals of brucinium 5-sulfosalicylate trihydrate (B5ST) were grown from ethanol–water (1:1) mixed solvent by slow evaporation method. Structure and crystallinity of the grown crystal were confirmed by single-crystal X-ray diffraction analysis. Presence of functional groups and coordination of brucine and 5-sulfosalicylic acid (5SSA) were confirmed by FT-IR and FT-Raman analyses. Optical transmittance spectrum shows the crystal having 90% transmittance in the visible region. The laser-induced surface damage threshold for the grown crystal was measured as 13.64 GW cm⁻² with Nd:YAG laser assembly. Dielectric study was performed on the single crystal to study the power dissipation of the material in the presence of alternating electric field. Crystal defects and surface morphology are studied by dissolution solvent technique and it reveals the layer growth mechanism for B5ST compound.
