Abstract

Tris (benzoylacetonato) technetium(III) and tris (2-thenoyltrifluoroacetonato) technetium(III) were synthesized by the direct reduction of pertechnetate with dithionite in the presence of excess ligands. The geometrical isomers of the benzoylacetonate were further separated by means of a silica gel column chromatography. In the silica gel system, the adsorption distribution coefficient of the tris (β-diketonato) technetium(III) decreases in the order of Tc(acac)3>fac-Tc(bzac)3>mer-Tc(bzac3)>Tc(tta)3.
