Abstract
Exposure of the solid zwitterion [Co-III (eta (5)-C5H4CO2H)(eta (5)- C5H4CO 2)] to hydrated vapours of volatile acids (HCl, CF3CO2H, HBF4) or bases (NH 3, NMe3, NH2Me) quantitatively produces the corresponding salts; the hetero geneous reactions are fully reversible, as the acid or base molecules can b e removed by thermal treatment, regenerating the starting material.
