Growth, optical, thermal and mechanical characterization of an organic crystal: Brucinium 5-sulfosalicylate trihydrate

Abstract

Single crystals of Brucinium 5-sulfosalicylate trihydrate (B5ST) were grown from ethanol-water (1:1) mixed solvent by the slow solvent evaporation method. X-ray powder diffraction analysis reveals that the crystal belongs to orthorhombic system with space group P 2 1 2 1 2 1. The various reflections were indexed and the lattice parameters were calculated. Photoluminescence (PL) shows peaks corresponding to protonation of the amino group. The optical absorption spectrum shows that the crystal has 90% transmittance in the visible region with a lower cutoff wavelength of 312 nm. Thermal analysis performed on the grown crystal indicates the thermal stability of the crystal and various thermodynamical parameters were calculated from the thermogravimetry (TG) data. The mechanical properties like Vickers microhardness number (H v), stiffness constant (C 11) and yield strength (σ v) of the crystal were estimated by Vickers hardness test.

Effect of NaCl Doping on Growth, Characterization, Optical and Dielectric Properties of Potassium Hydrogen Phthalate (KHP) Crystals

“…There is no significant change in peak but shift from 416 nm to 406 nm is observed with increase in dopent concentration, which shows the enhancement fluorescence which act as ligand. The intermolecular energy transfer is also facilitated which may enhance fluorescence [24] [25]. A peak at 493 nm and 498 nm corresponds to 3M% & 5M% doping of alkali metal.…”

Growth and Characterization of Benzimidazolium Salicylate: NLO Property from a Centrosymmetric Crystal

“…The researchers have reported recently Benzimidazole based organic compounds with good nonlinear properties such as 1H benzimidazolium hydrogen L-tartrate dihydrate [18], benzil doped Benzimidazole [19], benzimidazolium per chlorate [20]. Similarly salicylic acid forms salicylate salts with various organic molecules and forms salts through hydrogen bonding interactions like Urea salicylate, Bis Guanidinium 5 sulfosalicylate, and Brucinium 5 sulfosalicylate trihydrate and they are reported as efficient NLO materials [21][22][23]. The formation of hydrogen bonding in benzimidazolium organic complex salts was reported.…”
