摘要：

Time-resolved in situ energy-dispersive X-ray diffraction studies on the intercalation of dicarboxylate anions (Na2C4H4O4, Na2C6H8O4, Na-2-trans-C4H2O4, Na-2-cis-C4H2O4, Na-2-L-C4H4O5, Na-2-1,2-C8H4O4, Na-2-1,4-C8H4O4) into [LiAl2(OH)(6)]Cl . H2O have revealed the rapid formation of a second-stage intermediate phase that subsequently transforms into a phase-pure fully ion-exchanged product. These intermediates can be isolated as pure crystalline phases by reaction of the host lattice with stoichoimetric amounts of the dicarboxylate anions.
