Abstract：

A　series　of　new　Ln14-substituted　polyoxometalates,　H27Na16[(Ln14(H2O)W4(OH)O14)(WO4)4(GeW10O38)6]·nH2O　(n　≈　86)　(1-Ln,　Ln　=　Eu,　Gd,　Tb,　Dy,　Ho,　Er),　which　contain　14　Ln3+　and　6　{α(1,5)-[GeW10O38]12-}　units,　has　been　synthesized　in　one-pot　reactions.　As　the　first　14-Ln-containing　polyoxometalates,　the　octahedron-shaped　three-shell　structure　of　the　[(Ln14(H2O)W4(OH)O14)(WO4)4(GeW10O38)6]43-　polyanion　is　made　up　of　a　W4　tetrahedron,　a　Ln14W4　tetrahedron　and　a　Ge6W60　octahedron.　Compound　1-Dy　exhibits　frequency　dependent　magnetic　properties.　Compounds　1-Eu,　1-Tb　and　1-Dy　exhibit　the　characteristic　emission　bands　of　the　Ln3+　ion.　©　2019　The　Royal　Society　of　Chemistry.
