title: New oxorhenium(V) complexes with 2N2S donor sets and radiochemical behavior of their technetium analogs.
abstract: Oxorhenium(V) complexes of two thioether amines have been synthesized and characterized spectroscopically. The five-coordinated ReO(3+) moiety is satisfied by the amine compounds behaving as dibasic tetradentate (NSSN) ligands and a chloride ion. The radioanalytical studies of their technetium analogs have been carried out at different pH values in the range 3-10. The solvent extraction, TLC, electrophoresis and HPLC studies using (99m)Tc radiotracer indicate that the labeled complex with the TcO(3+) core is similar to the rhenium complex with the ReO(3+) core.
