One novel multidimensional organic–inorganic hybrid based on polyoxometalates and copper chlorine coordination polymers with 4,4′-bipyridine ligands

One novel organic–inorganic hybrid materials with 4,4′-bipy ligands and copper chlorine coordination polymers as linkers, with new topology, {[CuI(4,4′-bipy)]10Cl2(SiW12O40)2}·6H2O (1) (4,4′-bipy = 4,4′-bipyridine), has been hydrothermally synthesized. The single crystal X-ray structural analysis reveals that the structure of 1 is constructed from classical Keggin anions and [CuI(4,4′-bipy)] cations into a novel, three-dimensional (3D) polyoxometalates (POMs)based network. From the topological view, compound 1 is a novel (3.44.52.63)(32.44.56.69) topology. The electrochemical and photocatalysis properties of 1 have been investigated in details.
