Synthesis, crystal growth and characterization of a semiorganic material: Thiosemicarbazide potassium chloride

Thiosemicarbazide potassium chloride (K(NH2NHCSNH2)Cl·H2O) (TSCPC) is one of the potential semiorganic materials for many applications. The crystal growth of TSCPC by slow evaporation method at ambient temperature and its dimension was found to be (5 mm × 3 mm × 2 mm). The grown crystals where characterized by Fourier transform infrared spectroscopic (FT IR) analysis to find the different modes of vibration due to various functional groups present in TSCPC. The powder X-ray diffraction pattern of the grown crystal has been studied. Thermal stability of the grown crystal was identified at 185 °C by using TGA/DTA. The dielectric constant of the crystal was studied as a function of temperature with frequency and the results are discussed. The mechanical property of the grown crystal has been studied using Vicker's microhardness tester. The optical transmission spectrum was investigated to study its linear optical properties using UV–vis spectrophotometer.
