- Abstract
The assembly of gigantic heterometallic metal clusters remains a great challenge for synthetic chemistry. Herein, based on the slow release strategy of lanthanide ions and in situ formation of lacunary polyoxometalates, two giant 3d‐4f polyoxometalate inorganic clusters [LaNi12W35Sb3P3O139(OH)6]23− (LaNi12) and [La10Ni48W140Sb16P12O568(OH)24(H2O)20]86− (La10Ni48) are obtained. The nanoscopic inorganic cluster La10Ni48 possesses a super tetrahedron structure, which can be viewed as assembly from four LaNi12 molecules encapsulating a central [La6(SbO3)4(H2O)20]6+ octahedron core. This giant aesthetic La10Ni48 tetrahedron containing 214 metal ions is the largest 3d‐4f cluster reported thus far in polyoxometalate system. More interestingly, the LaNi12 and La10Ni48 display high stability in solution and La10Ni48 displays excellent proton conductivity.
