Structural overview of technetium compounds (2000–2004)

This paper provides an overview of the about 80 crystal structures of technetium complexes described in the past 5 years and exhibiting some peculiar structural features. In almost 90% of the compounds, technetium shows an odd oxidation number, and by a large majority the revised complexes are mononuclear and neutral. The review especially focuses on nitrido-Tc(V), oxo-Tc(V) and fac-[Tc(CO)3]+ complexes, which cover approximately one-half of the X-ray structural reports.
