A ternary rare earth coordination complex was synthesized directly in aqueous solution from lanthanum chloride, imidazole, glycine as raw materials. The preliminary characterization of the ternary complex was carried out by FTIR. Its spectrophotometric characteristics and solubility properties of the complexes were analyzed and compared with the ligands. Preliminary experimental results show that, compared with the ligands, various properties were altered for the complex. UV spectra show that compared with the L(希腊字母lambda)max of with free ligand glycine and imidazole, the L(希腊字母lambda)max of Rare Earth La and the ternary complex had blue shifted to various extend, which suggest La3+ and two ligands formed coordination bond. According to the conductivity data of the complex, La complex exists as an electrolyte in 1:3 ratios , indicating that the Cl - ion is outside of the complex, and the conductivity increases with the increase of temperature and concentration. The solubility of the complex differs from individual ligands, imidazole and glycine, the complex is more water soluble than in organic solvents. |
