| 英文摘要 | the tetra-capped keggin anion-supported cobalt-phenanthroline complex [co-2(phen)(2)(oh)(2)(h2o)(4)](0.5)[{co(phen)(2)(h2o)}(2)(asmo6mo2)-mo-vi (v)a(8)(iv)o(44)]center dot 2h(2)o (1) and the bicapped keggin anion-based nickel-phenanthroline compound [ni(phen)(2)h2o](2)[(asmo11moo40)-mo-vi-o-v((vo2)-o-iv)0.5]. 2h(2)o(2), have been hydrothermally synthesized and structurally characterized by elemental analyses, single crystal x-ray diffraction, ir and x-ray photoelectron spectrum. the interesting structural feature of 1 is that there are two types of free complex cation [co-2(phen)(2)(oh)(2)(h2o)(4)](2+) in different orientations in the crystal structure of 1, and these free complex cations coexist in the space between polyoxometalate clusters. the structure of compound 2 is very like compound 1 except that the keggin unit is bi-capped instead of tetra-capped. compounds 1 and 2 are examples that arsenicum-centered vanadomolybdate anion acts as an active building block in the fabrication of polyoxometalates-supported hybrid solids. then, the magnetic characteristic of i is typical of a dominant ferromagnetic interactions in the 6-300 k temperature range and a succedent antiferromagnetic interactions in the very low temperature range (2-6 k), while the magnetic behavior for 2 is characteristic of a dominant ferromagnetic interactions in the 6-300 k temperature range and succedent antiferromagnetic interactions in the very low temperature range (2-6 k).
