unit. On the basis of }1H and }1}3 C NMR spectra, which reveal coupling of the thallium nucleus with the respective carbon and hydrogen atoms, a structure is proposed which contains four carboxylato ligands bridging the PdTl unit and one apical ligand bonded to thallium. This structure does not involve a direct Pd-to-Tl bond. The dynamic }1H and }1}3C NMR spectra show in solution the occurrence
