摘　　要：A novel composite, [C16H36N][Cu（2,2-bipy）3][PW12O40]·CH3CN·H2O based on Keggin-type phosphotungstate, has been synthesized in acetonitrile at moderate temperature and then characterized by IR and single-crystal X-ray structural analysis. The crystal is of monoclinic system, space group P21/n with a = 20.489（4）, b = 17.249（3）, c = 23.723（4）A, β = 95.114（2）^o, V = 8350（3）A3, Mr = 3710.79, Z = 4, Dc = 2.952 g/cm^3, F（000） = 6676, μ = 16.808 mm^-1, the final R = 0.0551 and wR = 0.1269 for 9460 observed reflections with I 〉 20（I）. Interestingly, it is found that the structure unit contains two different cations of [C16H36N]^＋ and [Cu（2,2-bipy）3]^2＋.A novel composite, [C16H36N][Cu（2,2-bipy）3][PW12O40]·CH3CN·H2O based on Keggin-type phosphotungstate, has been synthesized in acetonitrile at moderate temperature and then characterized by IR and single-crystal X-ray structural analysis.
