A series of hybrid compounds based on polyoxometalates (POM), namely, [Ln 4 (pdc) 4 (H 2 O) 16 ][PMo 11 VO 40 ] · 2H 2 O ( 1 – 5 ) and [Ln 4 (pdc) 4 (H 2 O) 16 ][HPMo 10 V 2 O 40 ] · H 2 O ( 6 , 7 ) (Ln = La, Ce, Pr, Nd, Sm for 1 – 5 , respectively, and Ln = La and Ce for 6 and 7 , respectively; H 2 pdc = pyridine‐2,6‐dicarboxylic acid), were hydrothermally synthesized and characterized by IR spectroscopy, elemental analyses, XRD, and single‐crystal X‐ray diffraction analyses. In these compounds, the Keggin polyanions [PMo 12– x V x O 40 ] (3+ x )– ( x = 1, 2) are encapsulated as noncoordinating guests in the nonlinear channels of the 3D lanthanide–pdc‐based host framework with a 4 3 · 6 2 · 8 topology. Moreover, photoluminescent properties, electrochemical properties, and catalytic properties were investigated.
