Three inorganic-organic hybrid compounds based on Keggin polyoxometalate and transition metal complexes: crystal structures and electrochemical properties

摘要

Polyoxometalate (POM)-based coordination polymers, [Cu(L)_2][SiW_(12)O_(40)]-4pyH_2O (1), [Ag (py)_2]_4[SiW_(12)O_(40)] (2) and [Co(L)_3]_2[SiW_(12)O_(40)]-py'7H_2O (3) (L=pyridine-2-carboxylic acid, py=pyridine), have been obtained hydrothermally and characterized by elemental analyses, IR and single-crystal X-ray diffraction analyses. Electrochemical properties are also investigated.
