Technetium complexes electrochemistry

Introduction.—The organometallic chemistry of technetium and rhenium reported during 1974 has been surveyed. The ligand-induced redox reactions of rhenium halides have been reviewed, and the chemistry of cyanide complexes of Group Vila metals has received attention. The electrochemistry of technetium and rhenium has been the subject of two reviews, and a general monograph on the production, uses, and disposal of technetium has appeared. Recently published crystal structures of complexes of technetium and rhenium have been collated. ... 

The most extensively studied of the Group 7 porphyrins are the maganese complexes that can exist in up to four different oxidation states [23]. In fact, no electrochemistry of technetium porphyrins has yet been reported, and the electrochemistry of rhenium porphyrins has been limited to compounds of the type (P)HRe(CO)3 and (P)[Re(CO)3 2 where P = TPP, TMTAA or TAA [160-162],...
