摘要：

A new Li/Al layered double hydroxide, [LiAl2(OH)(6)]Cl.2H(2)O, having a rhombohedral layer stacking sequence has been synthesized by the reaction of the Al(OH)(3) polymorphs, bayerite and nordstrandite, with LiCl. As is the case with the hexagonal analogue, rhombohedral [LiAl2(OH)(6)]Cl.2H(2)O has been found to readily undergo anion exchange reactions with a range of dicarboxylate anions although these reactions differ significantly in that no crystalline staging intermediates could be isolated. The rhombohedral stacking is maintained in the dicarboxylate derivatives.
