چکیده انگلیسی
VO2+ ions doped chlorocadmiumphosphate, CdHPO4Cl·[H3N(CH2)6NH3]0.5 crystals were synthesized at room temperature by using an organic amine, Hexa Methylene Di Amine as a templating molecule. The prepared crystals were characterized by powder XRD and several spectroscopic techniques. The powder XRD data was indexed to monoclinic crystal system with the lattice parameters, a=0.429, b=0.772, c=1.622 nm and β=114.3°. The nature of doped VO2+ ions in the framework material has been identified by optical absorption and electron paramagnetic resonance techniques. FT-IR spectrum exhibited the characteristic vibrations of phosphate anions and hexane diammonium cations. Thermal studies revealed that the prepared crystals withstand its state up to 307 °C. EPR and optical absorption spectrum confirmed that the doped VO2+ ions entered the complex material as distorted octahedral site symmetry. The evaluated bonding parameters revealed a partial covalent bonding between the doped metal ions and ligands.
