A starting [Mg+Al+Cl] LDH, prepared by coprecipitation, was further anion-exchanged to incorporate a variety of anions in the interlayer domain: (Fe(CN) 6 ) 3؊ , (P 2 O 7 ) 4؊ , (V 2 O 7 ) 4؊ , (CrO 4 ) 2؊ , and (Cr 2 O 7 ) 2؊ . The resulting materials were fully characterized using classical techni
Magnesium-aluminum hydrotalcite-like compounds (with molar ratios of Mg/Al ranging from 2.1 to 3.6) containing both carbonate and nitrate anions in the interlayer space were synthesized by the co-precipitation method. The obtained materials were characterized with respect to structure (XRD and FTIR)
