The lamellar double hydroxide, abbreviated notation [CdCrCl], was prepared by reacting solid CdO with a solution of CrCl₃,6H₂O, then characterized by X-ray powder diffraction and IR spectroscopy. This new compound crystallizes in the hexagonal system with two layers in each elementary cell (2H polytype). The structure is described by the space group P6₃/mmc. Cell parameter values are a=3.33 and c = 15.71 . The exchange properties of the material have been studied with the anions NO₃⁻, CO₃²⁻ and SO₄²⁻.
