An inorganic-organic hybrid compound {[Cu(phen)(3)](2)PW11VO40 center dot 2H(2)O (1) has been hydrothermally prepared and structurally characterized by elemental analyses, IR, CV, TG, magnetic susceptibility measurements and single crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic space group C2/c with a =27.232(2) angstrom, b =25.351(2) angstrom, c =16.2748 (4) angstrom, beta = 105.20 degrees, V =10842.3 angstrom(3), Z =4, R-1 =0.0490 and wR(2) =0.1362. The structure of 1 exhibits a three-dimensional supramolecular network, formed by hydrogen-bonding and pi-pi stacking interactions. The three-dimensional network consists of one-dimensional honeycomb channels, which accommodate free water molecules. The size of the channel is 10.4 10.4 angstrom. Electrochemistry of 1 shows it undergoes three one-electron reversible redox processes. Variable-temperature magnetic measurements show typical antiferromagnetic interactions in the 2-300 K temperature range.
