Growth and Characterisation of new Semi Organic Crystal Bisthiourea Calciumacetate

Abstract

A novel bisthiourea calciumacetate was grown from saturated solution by slow evaporation solution growth technique at ambient temperature. The stoichiometric ratio of the compound was confirms by elemental analysis. The crystallinity of the compound was confirmed by the sharp and well defined Bragg peaks observed in the powder X-ray diffraction pattern. The UV-visible absorption study was studies to ascertain the optical property of the compound. The thermal stability and decomposition pattern of the compound were formulated using TG-DTA studies. The heating and cooling cycles observed in differential thermal analysis (DSC) indicates that the compound shows first order phase transition. The FTIR spectroscopic technique was used to find out the various characteristic absorption bands present in the compound. The number of protons environment of the compound was confirmed by the NMR spectral studies. The second harmonic generation (SHG) efficiency of the compound indicates that the compound has SHG efficiency twice than that of standard potassium dihydrogen
