摘要
A Keggin-type tungstohosphate compound [Cu^l（2,2＇-bipy）2]3[PW^Ⅵ12O40] 1 （bipy = bipyddine） was prepared by the hydrothermal method for the first time. Single-crystal X-ray diffraction revealed that 1 （C60H48Cu3N12O40PW12） crystallizes in the monoclinic system, space group P21/c with a = 16.9837（10）, b = 17.9732（13） c = 27.8701（13）A°, β = 96.1039（10）°, V = 8459.2（9） A°^3, Mr = 4004.89, Z = 4, Dc = 3.145 g/cm^3, μ = 17.089 mm^-1, F（000） = 7208, S = 1.005, the final R = 0.0469 and wR = 0.0827 for 10807 observed reflections （I 〉 2σ（I））. Compound 1 consists of one discrete normal Keggin polyanion [PW^Ⅵ 12O40]^3- and three isolated coordinated cations [Cu^1（2,2＇-bipy）2]^＋. Significantly, there exist three crystallographically independent asymmetric reduced copper （I） centers in 1. Furthermore, the compound shows strong photoluminescence property in solid state at room temperature.
