Abstract
A novel pseudosandwich-type polyoxovanadate, CoII 2{(VO2)CoIII(CoIIIL) 2[V5O16]2}·23H2O (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 {CoIII 3(1,3-pda)2} cluster coordinated by two lacunary Lindqvist polyoxovanadates [V5O18]. Polyoxoanion 1 contains three CoIII centers in its central metal set, which was first observed in the polyoxometalate chemistry. Further, two CoIII 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.
