  1. (1)

    The reaction of hydrated ceric oxide with hydrogen chloride in methyl alcohol under controlled conditions did not result in the isolation of hexachloroceric acid.

  2. (2)

    Hexachloroceric acid has been obtained as a crystalline product from the reaction of hydrated ceric oxide and hydrogen chloride in dioxane.

  3. (3)

    Conditions have been worked out for obtaining the crystals in a pure form. Analytical results agree with the formula H2CeCl6, 4 C4H8O2. It has not been possible to obtain the acid without the dioxane of solvation.

  4. (4)

    The pyridinium salt of the acid has been prepared, the analytical values agree with the formula (C5H5NH)2CeCl6 for the complex.
