中文摘要	Three inorganic-organic composite sandwich-type phosphotungstates [Ni(tepa)(H2O)](4)H-2[Ni-4(H2O)(2)(alpha-B-PW9O34)(2)]center dot 8H(2)O (1), (enH(2))(3)[Ni-2(H2O)(10)][Ni-4(H2O)(2)(alpha-B-PW9O34)(2)]center dot en center dot 8H(2)O (2) and (enH(2))(10)[Mn-4(H2O)(2)(alpha-B-PW9O34)(2)](2)center dot 20H(2)O (3) (tepa = tetraethylenepentamine and en = ethylenediamine) have been synthesized by the hydrothermal reaction of the trivacant Keggin polyoxoanion [alpha-A-PW9O34](9-) with Ni2+ or Mn2+ ions in the presence of tepa or en and structurally characterized by IR spectra, elemental analysis, thermogravimetric analysis and variable temperature magnetic susceptibility. X-ray crystallographic analyses indicate that they all contain the classical tetra-M sandwiched polyoxoanions [M-4(H2O)(2)(alpha-B-PW9O34)(2)](10-) (M = Ni2+ or Mn2+) and nickelorganoamine cations or organoamine cations work as the charge balance ions. The tetra-M clusters in 1, 2 and 3 exhibit the familiar structural type of a beta-junction at the sites of metal incorporation. The study of magnetic property of 1 is indicative of a typical ferromagnetic coupling between Ni2+ cations. (C) 2007 Elsevier Inc. All rights reserved.
