abstract A microporous cationic lanthanide-organic framework, [Ce(2)(pydc)(2)(Hpydc)(H(2)O)(2)]Cl center dot(9+y)H(2)O (where pydc(2-) is the diprotonated residue of 2,5-pyridinedicarboxylic acid), has been prepared under just 30 mm (total reaction time) by applying microwave heating. The microporous framework (ca. 43% of accessible volume) contains prominent channels (cross section ca. 12 x 7 angstrom(2)) running parallel to the [001] direction housing disordered charge-balancing chloride anions and water molecules of crystallization. The BET surface area of the degassed material was calculated as approximately 106 m(2)/g. The solvent could be partially exchanged by chloroform or benzyl alcohol by crystal immersion at room temperature over a period of several days. Structural details and robustness, and solvent exchange tests, were investigated by using in tandem X-ray diffraction (single-crystal and powder), electron microscopy (SEM and EDS), and FT-IR spectroscopy.
