| Abstract: | One new polyoxometalate compound connected via cobalt/potassium cations, namely H_5K{[Co(H_2O)_5]_2(H_2Mo_(3.24)W_(8.76)O_(42)}·19H_2O 1, was prepared and characterized by ele mental analysis and IR spectroscopy. Single-crystal X-ray diffraction analysis result reveals that anions of {[Co(H_2O)_5]_2(H_2Mo_(3.24)W_(8.76)O_(42)}~(6-) in compound 1 are linked by potassium cations to form one dimensional chain, based on which a three-dimensional network is further constructed with the help of hydrogen bonds. Crystal data: H_(67)Co_2KMo_(3.24)O_(72)W_(8.76), M_r = 3297.87, monoclinic, C2/c, a = 19.0126(10), b = 16.6025(5), c = 19.1908(10) (A), β = 106.713(1)°, V= 5801.8(5) (A)~3, Z = 4, D_c = 3.755 g/cm~3, F(000) = 5961,μ = 18.730 mm~(-1), R = 0.0569 and wR = 0.1437 (I>2σ(I)). |
