摘要

The rational development of the new radiopharmaceutics using complexes of technetium-99m (for diagnosis) and rhenium-186/188 (for therapy) at a very high dilution scale requires the control of the coordination chemistry of the long-lived technetium-99 isotope (~(99)Tc) avaible in ponderable quantities as well as cold rhenium (Re). The oxo and nitrido metallic model complexes in the oxidation state +V derived from precursors (Oxo-metal = M~V OCl_3(PPh_3)_2, M~V O(PMe_2Ph)_2Cl_3, M~V OCl_4 and Nitrido-metal = M~V NCl_2(PPh_3)_2, M~V N(PMe_2Ph)_2Cl_2, M~V NCl_4) whose inherent physicochemical and structural proprieties determine their particular stability and reactivity. In addition, the physicochemical and structural studies carried out on these complexes enable us to improve the performances of these radiopharmaceutics contributing thereby to the stability of their internal coordination sphere and creating an electronic environment influencing their affinity and specificity for target bodies.
