Abstract: The thiosemicarbazone of (E)-2-(4-chlorobenzylidene) hydrazine-1-carbothioamide (TSCCB) and Thiosemicarbazone of A-Oxodiphenylmethane (TSCBP) is an interesting of organic compound in the crystalline nature. The quartz glass which is grown slow evaporation method from the solvent methanol. The crystal dimension up to 14X6.5X4mm3 obtained by benzpphenone and both crystal sizes are the same. The harvested crystals were purified by repeated recrystallization. FT-IR spectroscopic study was carried out on the growth, recognize the fundamental function group. Optical absorption studied illustrate the low absorption in the entire UV and visible spectral. The UV-Visible Spectra are confirming the optical transparency. This is more helpful to use these crystals in option applications. The harvested crystals TSCCB and TSCBP were characterized by proton nuclear magnetic resonance and of 13C NMR spectra which show the molecular structure of the crystals. Thermal analysis is a very useful technique for material characterization it provides with various information about the studied materials such as thermal stability, crystallization, Purity and Structure. Its thermal stability for analysis in the crystal by TGA and DSC. The TGA and DSC confirm the decay of TSCCB at 210 oC and it confirms the grown crystal TSCBP is thermally stable up to 184.14 0C. It further confirms the grown crystal TSCCB and TSCBP is thermally stable up to 210 oC and 184.14 0C. The frequency was identified in the crystal that enough by dielectric properties. The second harmonic generation efficiency of the powdered TSCCB and TSCBP and was tested using Nd: YAG laser and it is found to be 6.1 and be ~0.8 times time of potassium dihydrogen phosphate and urea. The obtained data support the formation of the expected thiosemicarbazone structures and suggest potential stability for further coordination studies.
