英文摘要：

A new compound,[Cu（en）_2]_2·[W_（4.5）^ⅥW_2^ⅤV^ⅤV_（9.5）^ⅣO_（44）{Cu（en）_2（H_2O）}_2]·3H_2O （1, en=ethy- lenediamine） , was hydrothermally synthesized and characterized by elemental analysis, Fourier transform infrared spectroscopy （ FTIR ） , X-ray photoelectron spectroscopy （ XPS ） , electron paramagnetic resonance （ESR）, X-ray diffraction analysis（XRD）, thermogravimetric（TG） analysis and single-crystal X-ray diffrac- tion analysis. Compound 1 represents a 2D layer structure constructed from tetra-capped bi-supporting Keggin tungstovanadates and transition metal complexes. Adjacent layers are further interconnected into a 3D supra- molecular structure via hydrogen bonds. The magnetic susceptibility of compound 1 demonstrates the presence of ferromagnetic interactions. In addition, the photocatalytic activity of compound 1 for the phtodegradation of Rhodamine B（ RhB） was also investigated.
