Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A new cationic triazole‐based metal–organic framework encapsulating Keggin‐type polyoxometalates, with the molecular formula [Co(BBPTZ)₃][HPMo₁₂O₄₀]⋅24 H₂O [compound <bold>1</bold>; BBPTZ=4, 4′‐bis(1, 2, 4‐triazol‐1‐ylmethyl)biphenyl] is hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, powder X‐ray diffraction, and single‐crystal X‐ray diffraction. The structure of compound <bold>1</bold> contains a non‐interpenetrated 3D CdSO₄ (cds)‐type framework with two types of channels that are interconnected with each other; straight channels that are occupied by the Keggin‐type POM anions, and wavelike channels that contain lattice water molecules. The catalytic activity of compound <bold>1</bold> in the oxidative desulfurization reaction indicates that it is not only an effective and size‐selective heterogeneous catalyst, but it also exhibits distinct structural stability in the catalytic reaction system.</p> </abstract>
