Hydrothermal reactions of CeO2 with racemic tartaric acid (H2tar) at different temperature yielded two novel Cerium-Organic Framworks, [Ce2(tar)2(C2O4)(H2O)2]n·4nH2O (1) and [Ce2(tar)2(C2O4)(H2O)4]n (2). 1 displays an unprecedented fsx-4,5-P21/c topology, which contains hydrophilic channels constructed by triple helical chains along a axis; 2 exhibits a 2D layer framework with a binodal (3,4)-connected V2O5 network. Notably, in both 1 and 2, the oxalate ligands were in situ synthesized from H2tar.
