摘要
One new polyoxometalate compound connected via nickel/potassium cations, H8K{[Ni（H2O）5]2（H2Mo1.80W10.20O42）}Cl3·16H2O 1, was prepared and characterized by elemental analysis and IR spectroscopy. Single-crystal X-ray diffraction analysis results reveal that clusters of [Ni（H2O）5]2（H2Mo1.80W10.20O42）}^6-in compound 1 are linked by potassium cations to form one- dimiensional chains, based on which a three-dimensional network is further constructed via the hydrogen bonds of O…O and O…Cl. Magnetic measurements show that compound 1 has paramagnetic properties. Crystal data： H62Cl3KMo1.80Ni2O68W10.20, Mr = 3461.33, monoclinic, space group C2/c, a = 18.9291（19）, b = 16.6758（17）, c = 19.1064（19）A, β = 106.6880（10）°, V = 5777.1（10）A^3, Z = 4, Dc = 3.980 g/cm^3, F（000） = 6250, μ = 21.574 mm^-1, R = 0.0579 and wR = 0.1623 （Ⅰ 〉 2σ（Ⅰ））.
