A new 1-D chain-like organic-inorganic hybrid phosphotungstate based on tetra-Ni-sandwiched polyoxoanion, [Ni(en)(2)](2)[{Ni-3(en)(6)(H2O)(2)Ni-4(H2O)(2)(alpha-PW9O34)(2)}] center dot 7H(2)O (en ethylenediamine) (1), has been synthesized under hydrothermal conditions and characterized by IR spectrum, UV spectrum, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. 1 crystallizes in the triclinic P (1) over bar space group with cell parameters a = 13.232(4) angstrom, b = 15.591(5) angstrom, c = 15.701(5) angstrom, alpha = 112.804(5)degrees, beta = 92.159(5)degrees, gamma = 109.012(5)degrees, Z = 1, R-1 = 0.0588, wR(2) 0.1387. Compound 1 displays a 1-D chain-like architecture constructed by sandwich-type polyoxoanions and [Ni(en)(2)](2+) linkers. Magnetic measurement reveals that intramolecular ferromagnetic interactions exist in the tetranuclear {Ni4O16} cluster.
