Abstract
A new compound, [Cu2~(II)Cl(2,2'-Bipy)4]{[Cu~(II)(2,2'-Bipy)2][BW_(12)~(VI)O_(40)]}-2H2O (I) (2,2'-Bipy = 2,2'-bipyridine), has been hydrothermally synthesized and characterized by elemental analysis, infrared (IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), thermal gravimetric (TG) analysis, power X-ray diffraction (PXRD) and X-ray single-crystal diffraction analysis (CCDC no. 1936106). Compound I consists of a Keggin polyoxotungstate mono-supported Cu~(II)-2,2'-Bipy complex, a dinuclear Cl-bridged Cu(II) complex and two water molecules. The [Cu2 Cl(2,2'-Bipy)4]~(3+) unit is a counter ion which is anchored to the polyanion via non-covalent intermolecular interaction. In addition, the fluorescence and both the catalytic performance for the epoxidation styrene and the photocatalytic property for degradation of Rhodamine B (RhB), Methylene blue (MB) and RhB + MB aqueous solutions under UV irradiation of compound I have been investigated and shown good properties.
