| 摘 要： | A new hybrid polyoxometalate-based complex, Cu^I（phen）214（SiW12O40） （phen = 1,10-phenanthroline）, has been synthesized by hydrothermal method and characterized with the aid of elemental analysis, IR, UV spectra and thermal analysis studies. The result of X-ray crystallography analysis exhibits that the title compound crystallizes in the orthorhombic space group P212121, and the formula is C96H64N16Cu4SiW12O40. Crystal data： a = 18.3574（14）, b = 21.1952（16）, c = 27.992（2）A, Mr = 4570.08, V = 10891.4（14）A^3, Z = 4, Dc = 2.787 g/cm^3,μ = 13.478 mm^-1, R = 0.0364, wR = 0.0638 （I 〉 2σ（I）） and F（000） = 8360. The complex consists of one α-Keggin anion SIW12O40]^4- and four discrete Cu^I（phen）2]^＋ cations. The valence sum calculations for the Cu atoms suggest that all four Cu atoms are in the ＋1 oxidation state.

| Abstract: | A new hybrid polyoxometalate-based complex, CuI(phen)2]4(SiW12O40) (phen = 1,10-phenanthroline), has been synthesized by hydrothermal method and characterized with the aid of elemental analysis, IR, UV spectra and thermal analysis studies. The result of X-ray crystallo- graphy analysis exhibits that the title compound crystallizes in the orthorhombic space group P212121, and the formula is C96H64N16Cu4SiW12O40. Crystal data: a = 18.3574(14), b = 21.1952(16), c = 27.992(2)(A), Mr = 4570.08, V = 10891.4(14)(A)3, Z = 4, Dc = 2.787 g/cm3, μ = 13.478 mm-1, R = 0.0364, wR = 0.0638 (I > 2σ(I)) and F(000) = 8360. The complex consists of one α-Keggin anion SiW12O40]4- and four discrete CuⅠ(phen)2] cations. The valence sum calculations for the Cu atoms suggest that all four Cu atoms are in the 1 oxidation state. |
