A series of tungsten-vanadium clusters [Cu (en) 2] 2 [WVI4.5WV2VVVIV9.5O4 4 {Cu (en) 2 (H2O)} 2] · 3H2O (1, en = ethylenediamine) ), And its structure and structure were characterized by X-ray single crystal diffraction, elemental analysis, Fourier transform infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, valence bond calculation, X-ray photoelectron spectroscopy, electron paramagnetic resonance and magnetic analysis The results showed that compound 1 was synthesized by the double-supported four-cap Keggin structure [WVI4.5WV2VIV9.5O40 (VVO4) {Cu (en) 2 (H2O)} 2] 4-tungsten-vanadium cluster anions As the basic structural unit, with the four [Cu (en) 2] 2 complex cations by covalent bonds and weak bonds connected to form a two-dimensional layered structure, adjacent layers and hydrogen bonds into three-dimensional supramolecular network. The magnetic properties of compound 1 and the photocatalytic degradation of rhodamine B were studied.
