Abstract

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) , β = 95.114(2)°, V = 8350(3) 3, Mr = 3710.79, Z = 4, Dc = 2.952 g/cm3, F(000) = 6676, μ = 16.808 mm-1, the final R = 0.0551 and wR = 0.1269 for 9460 observed reflections with I 2σ(I). Interestingly, it is found that the structure unit contains two different cations of [C16H36N]+ and [Cu(2,2-bipy)3]2+.
