Reversible gas-solid reactions between the organometallic zwitterion [(η5-C5H4COOH)(η5-C5H4COO)CoIII] and vapors of trifluoroacetic and tetrafluoroboric acids

Exposure of the solid zwitterion [(η5-C5H4COOH)(η5-C5H4COO)CoIII] (1) to vapors of CF3COOH and HBF4 quantitatively produces the corresponding salts of the cation [(η5-C5H4COOH)2CoIII]+ (2), namely ...
