    • A yellow single crystal with dimensions of 0.28 x 0.24 x 0.22 mm 3 was selected for the structural analysis. Single-crystal structure determination by X-ray diffraction was performed on an R-axis RAPID IP diffractometer equipped with a normal focus, 18 kW sealed tube X-ray source (Mo Kα radiation, λ, 0.71073 Å, operating at 50 kV and 200 mA. Data processing was accomplished with the RAXWISH processing program. The structure was solved by the direct method and refined by full-matrix least squares on F2 using the SHELXL 97 software. All of the non-hydrogen atoms were refined anisotropically. The hydrogen atoms were located from difference Fourier maps.

    • Synthesis of [Ce(H2O)(DMF)6(W10O 32)I(DMF)(CH3CH2OH) 1: 8 mL of a DMF solution of, n-C4H9)4N]4W10O 32 (0.334 g) and 5 mL of a glacial acetic acid (HAc) solution of Ce2(C2O4)3 (0.054 g) were added dropwise to 2 mL of ethanol (EtOH) in succession, with stirring. The light yellow solution was stirred at 80°C for two hours. The resulting solution was filtered and allowed to evaporate in air at room temperature. Slow evaporation afforded light yellow crystals yield: 30% based on W, Elemental anal. Calcd: C, 9.008; H, 1.874; N, 3.198. Found: C, 9.123; H, 1.901; N, 3.278
