A new complex of thallium(ill) with the nitrogen donor ligand diethylenetriamine (dien) has been prepared and characterized by multinuclear NMR (H-1, C-13. Tl-205), infrared and Raman spectroscopy. and X-ray diffraction. In solution, the symmetric s-facial isomer of [Tl(dien)(2)](3+) is formed. This is a fluxional molecule even at low temperature (235 K): therefore, the different rotamers cannot be observed separately. A complete characterization of the complex is given from its non-trivial NMR spectra. The crystal structure of [Tl(dien)(2)](ClO4)(3).H2O shows u-facial geometry. where the coordination environment around thallium can be described as a distorted trigonal prism.
