| In this paper, a novel pesudosandwich-type polyoxovanadate has been isolatedCoII2{(VO2)CoIII(CoIIIL)2[V5O16]2}·23H2O (L=1,3-pda)……………………………(1)by conventional aqueous solution method and characterized by elemental analysis, IRspectrum, thermal gravimetric analysis and magnetism. Single crystal X-ray diffractionanalyses indicates that polyoxoanion1is composed of a {CoⅢ3(1,3-pda)2} cluster coordinatedby two lacunary Lindqvist polyoxovanadates [V5O18]. Polyoxoanion1contains three CoIIIcenters in its central metal set, which was first observed in the polyoxometalate chemistry.Further, two CoⅢions in polyoxoanion1are functionalized by two1,3-pda ligands resultingin a pesudosandwich-type polyoxovanadate-based organic-inorganic hybrid material, whichrepresents the first pesudosandwich-type polyoxovanadate decorated by two1,3-pda ligands... |
