New layered double hydroxides (LDHs) with the composition [MAI(4)(OH)(12)]Cl-2 center dot 1.5H(2)O (M=Co, Ni) have been prepared by reacting gibbsite, gamma-Al(OH)3, with the appropriate chloride salt in a synthesis in which the water of crystallization is the only solvent present and fully characterized. These LDHs have been shown to undergo facile anion exchange reactions with both organic and inorganic anions at room temperature making them comparable to other LDHs in this respect. Reactions under the same conditions with CuCl2 center dot 2H(2)O and ZnCl2 failed to form the desired LDHs but those with nitrate salts did lead to the formation of the previously reported [MAI(4)(OH)(12)]NO3)(2)center dot 1.5H(2)O (M=Co, Ni) compounds.
