A new 3D extended structural compound, (dpdo)(2)H(2){[Cu(2,2'-bipy)(2)](2)(P(2)W(18)O(62))}center dot 5H(2)O 1 (dpdo = 4,4'-bipyridine-N,N'-dioxide; 2,2'-bipy = 2,2'-bipyridine), has been hydrothermally synthesized and characterized by elemental analyses, IR, TG analyses, cyclic voltammetry, and single-crystal X-ray diffraction. Compound 1 is built up of [P(2)W(18)O(62)](6-) cluster as the structural motif covalently linked by [Cu(2,2'-bipy)(2)](2+) coordination complexes to yield the 1D chains, which are further in close contact forming a 3D supramolecular framework via aromatic pi-pi stacking interactions and extensive hydrogen-bonding interactions among polyoxoanions, coordinated 2,2'-bipy organic ligands, free dpdo organic molecules and lattice water molecules.
