A new complex based on decatungstophosphate and chelated copper atoms, [Hen][Cu(en)(2)(H(2)O)](2). {[Cu(en)(2)(H(2)O)] center dot [gamma-PW(10)O(36)]} center dot 9H(2)O (1) (en = ethylenediamine) has been synthesized by conventional methods and characterized by single crystal X-ray diffraction, IR spectra and electronic spectra. The structure analysis of 1 indicates that the complex contains a divacant polyanion {gamma-PW(10)O(36)](7-) connected with a chelated copper atom. Magnetic susceptibility measurement for I in the temperature range 2300 K reveals the occurrence of intermolecular anti ferromagnetic interactions between chelate copper (II) complexes at lower temperature.
