cqvip:An unusual inorganic-organic hybrid hexatungstate complex [Cu(phen)3][W6O19] 1 (C36H24 CuN6O19W6, Mr = 2011.20) was hydrothermally synthesized and characterized by single- crystal X-ray diffraction, IR spectrum, UV-VIS spectrum and elemental analyses. This compound crystallizes in the monoclinic system, space group C2/c with a = 19.1005(11), b = 11.2585(11), c = 20.2867(15) , β = 102.177(2)o, V = 4264.4 3, μ(MoKa) = 16.691 mm–1, Dc = 3.133 g/cm3, Z = 4, F(000) = 3628, the final R = 0.0338 and wR = 0.0798 for 4090 observed reflections with I > 2σ(I). The result of structure determination shows that the crystal structure is constructed from [W6O19]2– cluster anions and [Cu(phen)3]2+ complex fragments, which are held together into a three-dimen- sional network through hydrogen-bonding interactions.
