Tetrapropylammonium Tribromocupurate Complex[(C3H7)4N]CuBr3(II) - Synthesis, Thermal and Spectral Characterization

Abstract Due to their interesting physical properties like ferroelastic, ferroelectric and commensurate – incommensurate phases at low temperatures, the importance of ABX3 complex (A=univalent cation, NH4(+) and its alkyl derivatives; B= divalent transition metal cation and X=halogen) has been gained more interest in recent years. Materials in good crystalline form are needed in modern technologies using semiconductors, magnetic garnets and ultraviolet and infrared solid-state lasers. The TTPATBr-Cu complex type ABX3 was grown by a slow evaporation process at room temperature. The synthesised complex is characterised by an elementary analysis, powder X-ray diffraction, thermogravimetric and differential thermal analysis. The synthesised complex is analysed by FTIR, proton and carbon-13 NMR spectrally. Elemental analysis data obtained for the complex confirm the molecular formulae [(CH3CH2CH2)4N]2CuBr3(II). The IR spectrum of the complex confirms the presence of methyl and methylene groups in the complex. The IR spectra also confirm the presence of C-C and C-N bonds. The NMR spectra suggest the presence of N-propyl group in the complex. TG-DTG thermogram indicates that the final decomposition of the complex starts from 809°C to form the end product. The prepared complex can be used for optical and biological applications.
