A new polyoxotungstate-based {W_(72)V_(30)} spherical cage

摘要

We report the {W_(72)V_(30)} composed of 12 pentagonal {(W)W5} units and 30 [VO(H2O)]~(2+) linkers. This compound was characterized by the elemental analysis, thermogravimetry, X-ray diffraction analysis, spectroscopic methods (IR, UV/Vis, Raman), XPS, EPR, magnetic measurements and BVS calculations. This is the second member in the pentagonal ((W)W5}-based polyoxotungstate family.
