Abstract
A new Keggin polyoxotungstate-based complex, [Cu(pz)]3[PW12O40] (pz=pyrazine, 1), has been synthesized and characterized by elemental analyses, IR, TG, and X-ray single crystal diffraction. In complex 1, one Keggin polyoxoanion coordinated with six copper cations to form an interesting one-dimensional chain, which was further linked by arrays of Cu(pz)nn+ polymeric chains to construct high dimensional network. Topological analysis reveals that complex 1 exhibits a (4, 6)-connected three-dimensional framework with new topology (46·47)3 (46·66·83). Complex 1 shows good photocatalytic activity for the photodegradation of methyl orange in the presence of H2O2 under UV light irradiation.
