An organic-inorganic compound [Cu(2,2′-bpy)2][{Cu(2,2′-bpy)2}2W12O40(H2)]·4H2O (Mr = 4048.00) was prepared from the hydrothermal reaction of Na2WO4·2H2O, CuCl2·2H2O, 2,2′-bipyridine (2,2′-bpy) and H2O at 160 ℃ for 4 days. The compound crystallizes in the monoclinic system, space group P21/n with a = 18.9196(8), b = 20.4212(8), c = 21.8129(9) , β = 96.992(3)°, V = 8365.0(6) 3, Dc = 3.214 g/cm3, Z = 4, μ(MoKα) = 17.269 mm-1 and F(000) = 7324. Of the 119837 total reflections, 17315 were unique (Rint = 0.0489). The final R = 0.0385 and wR = 0.0770 for 11142 observed reflections with I > 2σ(I). Single-crystal X-ray diffraction reveals that the structure is composed of [{Cu(2,2′-bpy)2}2W12O40(H2)]2- anions, discrete [Cu(2,2′-bpy)2]2+ cations and lattice water molecules, and the anion is made up of a {W12O40(H2)}6- α-Keggin core decorated with two {Cu(2,2′-bpy)2}2+ groups through bridging oxygen atoms.
