Technetium carboxylate complexes--II. Structural and chemical studies.
Formate, acetate, and pivalate based complexes of technetium have been prepared by the electrochemical reduction of pertechnetate in the appropriate carboxylate buffer. Also, chemical synthetic routes to these complexes have been explored using technetium chloro compounds of known oxidation states as starting materials. The technetium carboxylate complexes were selectively examined by subtractively normalized interfacial Fourier transform infrared, electron spin resonance, and electronic spectroscopy, electrochemistry, electrophoresis, and anion exchange chromatography. These complexes have been proposed to be metal-metal bonded dioxo bridged ditechnetium(IV) species with axial and bridged carboxylate ligands.
