Elektrisch leitfähiges μ-Cyano(tetrabenzoporphyrinato)cobalt(III)/ Electric Conductive Electric Conductive //-Cyano(tetrabenzoporphyrinato)cobalt(III)-Cyano(tetrabenzoporphyrinato)cobalt(III)

The preparation of tetrabenzoporphyrinatocobalt(II) and tetrabenzoporphyrinatocobalt(III)- cyanide derivatives either with terminal or bridging cyanide is described. The IR and the 1H NMR spectra as well as magnetic measurements are in accordance with the proposed structures and the oxidation states of the complexes. μ-Cyano(tetrabenzoporphyrinato)cobalt(III) (4) exhibits a powder conductivity of σRT = 4 ·10-2 S/cm, without additional external doping.
