Synthesis And Properties Of Rare Earth (Er, Eu) Transition Metal (Cu, Zn) Carboxylate Organic Coordination Compound

Rare earth complexes have potential applications in the field of catalytic,biological medicine?antibacterial?,animal feed,micronutrient fertilizer,magnetic materials and fluorescent materials due to their complicated structure and many excellent properties.Synthsis and applications of the rare earth complexes have been taken more and more attention.Rare earth complex and rare earth-transition metal heterometallic coordination polymers were synthesized.Their structures,properties were studied in this thesis.The main work is as follow:?1?The rare earth binary complexes Eu₂?Gly?₆·?H₂O?₄·?Cl O₄?₆ and Er₂?Gly?₆·?H₂O?₄·?ClO₄?₆ were synthesized by using Eu³⁺ions and Er³⁺ions with glycine in aqueous solution,respectively.X-ray diffraction ana lysis was carried out on the above two kinds of products to know its crystal structure,and the latter were analysised by differential scanning calorimetry and thermogravimetric to learn its thermodynamic properties.The rare earth binary complex[Er?PDA?₂·?H₂O?₂]·4H₂O were synthesiz ed by hydrothermal synthesis using Er³⁺ion and pyridine-2,6-dicarboxyli c acid.X-ray diffraction analysis was carried out on the products to kn ow its crystal structure,and thermodynamic properties were analysised by differential scanning calorimetry and thermogravimetricanalysis.?2?The rare earth ternary complex Eu?Glu??Im?₅?Cl O₄?₃·3HCl O₄·6H₂O were synthesized by using Eu³⁺ion and glutamic acid with imidazol e in aqueous solution.The infrared characterization and X-ray single cr ystal diffraction showed its crystal.The thermal analysises of the produ ct were carried out by adiabatic calorimetry,differential scanning calori metry and thermogravimetric analysis.?3?The rare earth heteronuclear complex[Eu₄?PDA?₆Cu?ClO₄?₂]n·H₂O was synthesized by hydrothermal synthesis using Eu³⁺ions and Cu²⁺ions and pyridine-2,6-dicarboxylic acid.Its crystal structures were com prehensively analyzed.The rare earth heteronuclear complex[Er Zn₆??₃-O H?₃??₃-Gly?₆]?ClO₄?₄?Cl O?₂·2H₂O was synthesized by using Er³⁺ions?Z n²⁺ion and glycine in aqueous solution.The crystal structure,the magn etic properties,fluorescence emission spectra,differential scanning calori metry and thermogravimetric analysis were carried out..
