A new coordination polymer, H[{Ce(H2O)(5)}(2){Ce(pdc)(2)(H2O)(4)}{Ce(pdc)(3)}(PW12O40)]center dot 2H(2)O 1 (pdc = pyridine-2,6 -dicarboxylate), has been obtained by the hydrothermal reaction. It exhibits a 3D hydrotalcite-like structure constructed from 2D cationic [{Ce(H2O)(5)}(2){Ce(pdc)(2)(H2O)(4)}{Ce(pdc)(3)}](2+) layers pillared by alpha-Keggin [PW12O40](3-) anions. Polymer 1 is active for photocatalytic H-2 evolution under UV irradiation.
