Dithiocarbamate complexes nitrides

Prior to 1980, dithiocarbamate complexes of technetium were unknown. However, over the past 20 years considerable developments have been made, driven mainly by the application of technetium(V) nitride complexes in radiopharmaceuticals. More recently, dithiocarbamate chemistry of technetimn has been more fully explored with diphosphine, carbonyl, oxo, imido, and other ligand combinations. 

The first rhenium dithiocarbamate complexes, [ReClaCSaCNRa)], were not reported until 1960 (1181), and even then, it was not until the 1970s that substantial inroads were made. Now, dithiocarbamates are known to stabilize rhenium in oxidation states +1 to +5, with the latter being the most common, and the chemistry is dominated by strong jt-donor ligands such as oxo and imido, and especially prevalent are nitride complexes.
