| مستخلص: |
Two supramolecular compounds based on Keggin polyoxotungstates, (4,4′-H2bpy){[Cu(4,4′-bpy)]2[SiW12O40]} (1) and (4,4′-H2bpy)2[SiW12O40]·2H2O (2) have been synthesized and characterized by elemental analyses, IR, UV, XPS spectra, TG analyses, and single crystal X-ray diffraction analyses. Compound1exhibits an infinite 1-D ladder like structure, which is further interconnected into a 3-D supramolecular frameworkviahydrogen bonding interactions. Compound2contains 4,4′-bipyridine (4,4′-bpy), pseudo-Keggin polyoxoanions [SiW12O40]4−, and water molecules. Polyoxoanions together with water molecules in2construct a 3-D inorganic supramolecular network through O···O and O···Ow(1) interactions. The electrochemical behaviors and photocatalytic properties of1and2have been investigated. [ABSTRACT FROM PUBLISHER] |
