Synthesis and characterization of an inorganic-organic hybrid copper coordination polymer based on well-defined Keggin polyanions

A new inorganic-organic hybrid complex based on well-defined Keggin-type polyoxometalates and copper-lutidine assemblies, namely, [Cu-3(3,5-Lutidine)(6)(PW12O40)](n) (1), has been obtained under hydrothermal conditions and characterized by elemental analysis and single crystal X-ray diffraction. The X-ray diffraction analysis reveals that compound 1 is three-dimensional (3D) supramolecular structure with 'sql' topological 2D layer. The photocatalytic experiments indicate that 1 exhibit good catalytic activity for photodegradation of Rhodamine B (RhB) with UV irradiation. The thermal stabilities and fluorescent properties of this complex have also been studied. (C) 2018 Elsevier B.V. All rights reserved.
