A novel complex of monomeric thallium(Ⅲ) with the nitrogen donor ligand phenanthroline (phen) has been prepared and characterized by multinuclear NMR (1H, 13C, 205Tl).The three complexes exist in equilibria in DMSO and acetonitrile solution, which was proved by the 205Tl NMR spectra. The 1H and 13C NMR spectra of tris-phen Tl(Ⅲ) complex have been measured, where the spin-spin coupling between Tl (l=1/2) and 13C or 1H signals were observed with the 1H and 13C NMR spectroscopy in acetonitrile. The coupling constants are presented and the chemical shifts of complexes are discussed in detail.
