Abstract: | Single crystals of dihydroxylammonium tetrachlorostrontium(II) dihydrate were grown by slow evaporation solution growth method at ambient temperature. The suitability of this material for optical application was studied by UV–visible absorption and optical transmittance spectroscopic techniques. The powder X-ray diffraction (XRD) method was used to confirm the crystalline nature of the compound and it is observed that the compound crystallized in orthorhombic system. The thermal stability of the title compound was studied by thermogravimetry and differential thermal (TG–DTA) analyses. The thermal anomalies observed in the low temperature differential scanning calorimetry (DSC) study indicate the occurrence of the first order structural phase transitions in the compound. The FTIR spectrum characterizes the various chemical bonding and water molecules in the compound. The nonlinear optical property of the material was analyzed by modified Kurtz–Perry powder technique. The dielectric constant and dielectric loss of the compound decreases with increase in frequency. |
