The synthesis of a Keggin-type polyoxotungstate-coordinated diplatinum(II) complex, [(CH(3))(4)N](3)[alpha-PW(11)O(39){cis-Pt(NH(3))(2)}(2)]. obtained by reaction of Keggin-type mono-lacunary polyoxotungstate, [alpha-PW(11)O(39)](7-), with cis-diamminedichloroplatinum(II) in an aqueous solution is described. The complex was characterized by elemental analysis, thermogravimetric/differential thermal analysis (TG/DTA), Fourier transform infrared (FTIR), ultraviolet-visible (UV-vis), and solution (1)H, (31)P, and (183)W nuclear magnetic resonance (NMR) spectroscopy. The two cis-platinum(II) moieties, [cis-Pt(NH(3))(2)](2+), were coordinated each to two oxygen atoms in a mono-vacant site of [alpha-PW(11)O(39)](7-) with C, symmetry, and the cis-conformation was highly stable in dimethylsulfoxide and water.
