A novel 2D layer structural compound constructed from tetra-capped pseudo-Keggin heteropolytungstates interacting with copper coordination fragments: [Cu(en)2(H2O)]2[Cu(en)2]2[AsW2VIW7VV7IVO44]·2H2O

A novel polyoxometalate [Cu(en)2(H2O)]2[Cu(en)2]2 [AsW9V7O44] · 2H2O (1) has been hydrothermally synthesized and characterized by elemental analysis, IR spectrum, XPS spectrum and single crystal X-ray diffraction analysis. It is the first example of two-dimensional layer structure constructed from four vanadium-capped pseudo-Keggin tungstates. The study of the magnetic susceptibility of 1 demonstrates the presence of ferromagnetic interactions.
