三异金属配合物和V-型羧酸配合物的合成、晶体结构及磁性研究的开题报告 Title Synthesis, Crystal Structure and Magnetic Properties of Three Metal Complexes and V-type Carboxylate Complexes Introduction Metal complexes have been widely used in materials science, catalysis, and medicine due to their unique properties. Among them, tri-metal complexes and V-type carboxylate complexes are two important types of complexes. The tri-metal complexes refer to complexes containing three different metal elements, while V-type carboxylate complexes refer to complexes with a carboxylate ion bridging two metal ions in a V shape. The research on these complexes has attracted much attention due to their diverse applications in biological and technological fields. Objectives The main objectives of this research are: - To synthesize and characterize three metal complexes with different metals (Au, Pd, and Tl) and to study their crystal structure and magnetic properties. - To synthesize and characterize V-type carboxylate complexes using different organic acids as ligands and to investigate their crystal structure and magnetic properties. Methods The synthesis of the three tri-metal complexes will be carried out using the solvothermal method. The metal precursors, ligands, and solvents will be mixed in a specific ratio and heated under a controlled temperature and pressure for a certain period to obtain the complex. Various characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy will be used to characterize the complexes. The synthesis of V-type carboxylate complexes will be carried out using the same method. Different organic acids such as phthalic acid, oxalic acid, and malonic acid will be used as ligands to form the complexes. The complexes will then be characterized using the same techniques. The magnetic properties of the complexes will be studied using a superconducting quantum interference device (SQUID
