摘要
A novel pseudosandwich-type polyoxovanadate, Co-2(II){(VO2)Co-III((CoL)-L-III)(2)[V5O16](2)}center dot 23H(2)O (1) (L = 1,3-propanediamine, 1,3-pda), has been isolated using a conventional aqueous solution method and characterized by elemental analysis, IR spectrum, thermal gravimetric analysis and magnetism. Single crystal X-ray diffraction analyses indicate that polyoxoanion 1 is composed of a {Co-3(III)(1,3-pda)(2)} cluster coordinated by two lacunary Lindqvist polyoxovanadates [V5O18]. Polyoxoanion 1 contains three Co-III centers in its central metal set, which was first observed in the polyoxometalate chemistry. Further, two Co-III ions in polyoxoanion 1 are functionalized by two 1,3-pda ligands resulting in a pseudosandwich-type polyoxovanadate-based organic-inorganic hybrid material, which represents the first pseudosandwich-type polyoxovanadate decorated by two 1,3-pda ligands.
