摘要：

Two novel heteropolytungstates, [Ni(2,2 '-bpy)(3)](1.5){PW(10.7)9V(1.21)O(40)(VO)(0.5)[Ni(2,2 '-bpy)(2)L]} center dot 0.5H(2)O (1) (2,2 '-bpy = 2,2 '-bipyridine, L = 0.5H(2)O + 0.5OH(-)) and K[PW12O40[Ni(1,10-phen)(2)(OH)](2)] center dot 2H(2)O (2) (1,10-phen = 1,10-phenanthroline), have been synthesized under hydrothermal conditions and characterized by IR, XPS, and X-ray diffraction analyses. The polyoxoanion of 1 is a mono-capped alpha-Keggin cluster which supports a metal coordination fragment [Ni(2,2 '-bpy)(2)L](1.5+), while the structure of 2 exhibits a 1D chain constructed from pseudo-Keggin cluster bi-supported transition metal complexes linked by K+ ions. Studies of magnetic properties indicated the presence of paramagnetic behaviours for compounds 1 and 2. (C) 2007 Elsevier B.V. All rights reserved.
