SUMMARY:
The synthesis and characterization of the following two oxamate type ligands: 4- methylphenylene(oxamate), hereby named 4-mpo, and tetrabutylammonium N-4- methylphenylene(oxamate), named Bu4N+(4-mpo) is herein described. These ligands were used for preparing four coordination complexes with lanthanide ions Gd(III), Tb(III), Dy(III) and Ho(III). The achieved coordination compounds were characterized via infrared vibrational spectrometry, thermogravimetric analysis, polycrystal X-ray diffraction, elemental analysis and melting point. The structure of the dysprosium-based compound was elucidated by X-ray diffraction techniques. Optical property studies were performed and the quantum yield of the coordination compounds in solution and in solid were determined.
