文摘

A new inorganic–organic supramolecular polymer, i.e. [MoO₂Cl₂(H₂O)₂]·Hdpa·Cl·H₂O (1) (where Hdpa stands for 2,2′-dipyridylammonium), has been synthesised and characterized, including by single-crystal X-ray diffraction studies. 1 is constituted of inorganic [MoO₂Cl₂(H₂O)₂] moieties associated to organic Hdpa units via hydrogen bonds. The combination of hydrogen-bonding and π–π stacking interactions gives rise to a remarkable 3D framework. Compound 1 is an effective catalyst for the H₂O₂-mediated epoxidation of cyclooctene at 50 °C.
