Synthesis, Spectral Properties of Tb (III) Complexes with 2，2'-Dithiosalicylic Acid

Abstract:

A new terbium complex with aromatic multicarboxylate ligand, 2, 2'-dithiosalicylic acid (L), has been synthesized. The terbium complex was characterized by elemental analysis, infrared spectrum and luminescent spectra, and the complex conforms to 1:1 metal-to-ligand stoichiometry. The complex is stable in air. The results show that the Tb (III) ion in the complex is coordinated by oxygen atoms of the ligand and the oxygen atoms of the nitrate and coordinated water molecules. The luminescent properties of terbium complex have also been investigated in solid state and in organic solvents.
