Abstract: Two new cerium mixed carboxylate porous metal-organic frameworks, [Ce2(fum)3(H2O)4?(bdc)?(H2O)2]n (1) and [Ce2(suc)2(ox)(H2O)4?(H2O)4]n (2) were synthe- sized by hydrothermal method with two kinds of carboxylic acid, respectively. They were characterized by elemental analysis, IR, TGA-DTA and single-crystal X-ray diffraction. Single-crystal X-ray diffraction indicates that complexes 1 and 2 are both 3D porous metal-organic frameworks with pillared layers. Complex 1 possesses a 3D framework structure consisting of Ce-fumarate layers pillared by fumarate ligands with intersected channels in two directions between the layers occupied by uncoordinated neutral p-benzenedicarboxylic acid and lattice water molecules. Similar to complex 1, complex 2 is a 3D structure with Ce-succinate layers pillared by oxalate ligands, which shows intersected channels in three directions between the layers filled with lattice water molecules.
