A meta-stake precursor Cs0.29CoO2‧1.12H2O was prepared by a molten salt method and utilized in the ion exchange reaction. Ion exchange with high concentration of cobalt hexamine trichloride solution results a novel hydrogen-bonded structure [Co(NH3)6]0.0605Cs0.107CoO2. With the ability to sustain a greatly expanded structure in oxidation environment, the novel structure provides the opportunities for preparing a series of ions exchanged product and applying as the catalyst matrix for oxidation reaction. The structural stability of this novel compound was characterized by cyclic voltammetry
