A new inorganic 2D network polyoxometalate constructed from Wells–Dawson phosphomolybdate linked through Cu(II) ions

A novel compound based on saturated Wells–Dawson type phosphomolybdate, [Cu(H2O)4]3[P2Mo18O62]·12H2O (1) has been synthesized by the conventional solution method and characterized by elemental analysis, IR spectrum, UV spectrum, thermogravimetric analysis, electrospray ionization mass spectrometry (ESI-MS), electrochemistry and single-crystal X-ray diffraction. X-ray structural analysis reveals that 1 exhibits the 6-connected 2D topological network with the Schläfli symbol of (3649).
