Actinide bis(porphyrinate). pi. -radical cations and dications, including the x-ray crystal structure of ((TPP)/sub 2/Th)(SbCl/sub 6/)
The chemistry of actinide porphyrin complexes remains in large part undeveloped. The authors report here the first synthesis, isolation, and detailed characterization of several actinide bis-porphyrin sandwich complexes, including the neutral, ..pi..-radical monocation, and ..pi..-radical dication complexes, ((TPP)/sub 2/M)/sup n+/, where M = Th(IV) or U(IV) and n = 0, 1, or 2. In addition, the x-ray crystal structure of both the neutral Th complex and its oxidized ..pi..-radical cation, ((TPP)/sub 2/Th)(SbCl/sub 6/0, have been solved. These complexes are among the very first ..pi..-radical cations where close interaction between two porphyrins occurs. Moreover, these complexes belong to an unusual class of actinide complexes where redox processes can occur in near proximity to the f-element.
