Abstract
- The first series of niobium-tungsten-lanthanide (Nb-W-Ln) heterometallic polyoxometalates {Ln<subscript>12</subscript>W<subscript>12</subscript>O<subscript>36</subscript>(H<subscript>2</subscript>O)<subscript>24</subscript>(Nb<subscript>6</subscript>O<subscript>19</subscript>)<subscript>12</subscript>} (Ln=Y, La, Sm, Eu, Yb) have been obtained, which are comprised of giant cluster-in-cluster-like ({Ln<subscript>12</subscript>W<subscript>12</subscript>}-in-{Nb<subscript>72</subscript>}) structures built from 12 hexaniobate {Nb<subscript>6</subscript>O<subscript>19</subscript>} clusters gathered together by a rare 24-nuclearity sodalite-type heterometal-oxide cage {Ln<subscript>12</subscript>W<subscript>12</subscript>O<subscript>36</subscript>(H<subscript>2</subscript>O)<subscript>24</subscript>}. The Nb-W-Ln clusters present the largest multi-metal polyoxoniobates and a series of rare high-nuclearity 4d-5d-4f multicomponent clusters. Furthermore, the giant Nb-W-Ln clusters may be isolated as discrete inorganic alkali salts and can be used as building blocks to form high-dimensional inorganic-organic hybrid frameworks.
