Inorganic-organic hybrid with 3D supramolecular channel assembled through C-H center dot center dot center dot O interactions based on the decavanadate
A novel compound, [Cu(2,2'-bipy)(2)](2)[H2V10O28}center dot(2,2'bipy)center dot 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.
