A series of 3D polyoxometalate (POM) based coordination polymers, namely, Ln 4 (pdc) 4 [SiW 12 O 40 ] · x H 2 O (Ln = Eu, Gd, Tb, Dy; x = 19, 13, 14, 18; H 2 pdc = pyridine‐2,6‐dicarboxylate), have been hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, thermogravimetric analyses (TGA), XRD, and single‐crystal X‐ray diffraction analyses. Single‐crystal X‐ray diffraction reveals that they are all isostructural, and the Keggin polyanions [SiW 12 O 40 ] 4– are wrapped as noncoordinating guests in the nonlinear channels of the 3D host framework with 4 3 · 6 2 · 8 topology that is formed by rare‐earth metal ions and organic ligands. Furthermore, cyclic voltammetry (CV), ethanol‐sorption properties, and catalytic properties are also discussed.
