Abstract Reactions of [99TcNCl4]− with ethylenediaminetetraacetic acid (EDTA) and ethylenediamine-N, N′-diacetic acid (EDDA) in a mixture of water and acetone gave TcVIN-EDTA and TcVIN-EDDA complexes. The infrared spectra of both reaction products showed the existence of the Tc≡N and C=O groups. The elemental analysis indicated the 1∶1 TcN-ligand ratio in the EDTA and EDDA complexes. Electrophoresis showed that the TcVI-EDTA complex was an anionic species in a perchlorate solution. For the TcVIN-EDDA complex, neutral and anionic species were formed, depending on the pH of the solution. Formation of the μ-oxo dimer complexes was suggested from the UV-Vis absorption spectra.
