Teta—see Acetic acid, tctramethylenediaminetetra-Technetium complexes cupferron, 510 phthalocyanines, 866 polypyrazolylborates, 251 porphyrins, 826 pseudohalides, 229, 230 Tellurium... 

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],...
