摘要:The title compound,Tetrakis(hydrazine) barium(II) chloride monohydrate (TBCM) was crystallised by solvent evaporation- solution growth technique. Energy dispersive analysis of X-ray (EDAX) and elemental analysis confirmed the stoichiometry of the compound. FTIR spectral study has been performed to identify the presence of various functional groups. The optical transmittance window and the lower cut off wavelength of the TBCM have been identified by UV-Vis-NIR studies. The proton configuration of TBCM is confirmed by 1H NMR Spectroscopy. The sharp Bragg peaks of powder X-ray diffraction pattern show crystalline nature of the compound. Thermogravimetry (TG), Differential thermal analysis (DTA) and low temperature differential scanning calorimetry (DSC) were used to study thermal properties of the compound. Kurtz powder test with Nd:YAG laser radiation shows a considerable second harmonic generation by TBCM. Keywords: FT-IR; NLO; NMR; Solvent evaporation; Thermogravimetry.
