Factors influencing staging during anion-exchange intercalation into [LiAl2(OH)(6)]X center dot mH(2)O (X = Cl-, Br-, NO3-)
A variety of organic carboxylates and phosphonates have been intercalated into the hexagonal and rhombohedral polymorphs of [LiAl2(OH) 6]X·mH2O, with X = Cl-, Br-, and NO3-. The two classes of polytype differ in the stacking sequence of the layers (aba and abca, respectively). Both the initial inter...

| description | A variety of organic carboxylates and phosphonates have been intercalated into the hexagonal and rhombohedral polymorphs of [LiAl2(OH) 6]X·mH2O, with X = Cl-, Br-, and NO3-. The two classes of polytype differ in the stacking sequence of the layers (aba and abca, respectively). Both the initial interlayer anion and the stacking sequence of the host are seen to have a profound effect on whether anion-exchange intercalation reactions occur in a one-step direct transformation from the host to the first-stage intercalated product, or whether the reaction proceeds via a second-stage intermediate. Generally, staging is much more prevalent in the hexagonal system, and with the harder to replace Cl- and Br- anions. Overall, the occurrence of staging appears to be strongly correlated with the rate of anion exchange in these materials. © 2005 American Chemical Society. |
