Inorganic–Organic Hybrid with 3D Supramolecular Channel Assembled through C–H···O Interactions Based on the Decavanadate

Abstract

Abstract A novel compound, [Cu(2,2′-bipy)2]2[H2V10O28]·(2,2′-bipy)·H2O (1) has been synthesized and characterized by elemental analyses, IR, UV, and single crystal X-ray diffraction. Compound 1 is made up of supramolecular layers of polyoxoanion-supported copper complexes pillared by individual [H2V10O28]4− clusters via weak C–H···O hydrogen-bonding interactions forming a three-dimensional microporous framework with two types of channels, and the “guest” bipyridine molecules reside in the channels.
