| Abstract: | Abstract The reaction of 2-pyridine carboxylic acid (Hpic) with (n-Bu4N)TcNCl4] and (n-Bu4N)TcOCl4] in ethanol and methanol, respectively, yields the dinuclear μ-oxo complex (pic)2NTc-O-TcN(pic)(Hpic)Cl] and the monomeric complex TcO(pic)2Cl]. Visible and infrared spectroscopy, ESR, 1H-NMR and 99Tc-NMR have been used to characterize the new compounds. The most important field of application for the new compounds synthesized is radiodiagnostics. |
