A novel polyoxometalate-based composite compound [Ni(phen)2][Hphen](AsW12O40) (phen = 1,10-phenanthroline) 1 has been hydrothermally synthesized and characterized by elemental analysis, IR, TGA, ESR spectroscopy and single-crystal X-ray diffraction. Each structure unit of 1 consists of one polyoxoanion AsW12O403-, one free phenanthroline molecule and one coordination cation [Ni(phen)2]2+. The title compound crystallizes in the orthorhombic system, space group P212121, with a = 12.2383(7), b = 21.0884(11), c = 22.3237(12) , V = 5761.4(5) 3, Mr = 3520.44, Z = 4, Dc = 4.059 g/cm3, F(000) = 6204, μ(MoKα) = 24.844 mm-1, GOF = 1.022, the final R = 0.0376 and wR = 0.0742 (I > 2σ(I)) for 865 parameters and 9637 observed reflections with I > 2σ(I).
