Abstract

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.

A new solvated polyoxometallate bearing an amino acid, (I), has been prepared for the first time by the reaction of 0.16 mmol α-H 4 SiW 12 O 40 .15H 2 O with 0.78 mmol of L-proline in hydrochloric acid at pH 3. The structure of (I) was substantially characterized by some physical approaches, such as
