Synthesis of Isotypic Giant Polymolybdate Cages for Efficient Photocatalytic C-C Coupling Reactions.

The construction of isotypic high-nuclearity inorganic cages with identical pristine parent structure and increasing nuclearity is highly important for molecular growth and structure-property relationship study, yet it still remains a great challenge. Here, we provide an in situ growth approach for successfully synthesizing a series of new giant hollow polymolybdate dodecahedral cages, , , and , whose structures are growth based on giant polymolybdate cage . Remarkably, they show two pathways of nuclear growth based on , that is, the growth of 10 and 20 Mo centers on the inner and outer surfaces to afford and , respectively, and the growth of 10 Mo centers both on the inner and outer surfaces to give .

Structural Evolution of Giant Polyoxometalate: From "Keplerate" to "Lantern" Type Mo for Improved Oxidation Catalysis.

Structural variants of high-nuclearity clusters are extremely important for their modular assembly study and functional expansion, yet the synthesis of such giant structural variants remains a great challenge. Herein, we prepared a lantern-type giant polymolybdate cluster (L-Mo ) containing equal metal nuclearity with the famous Keplerate type Mo (K-Mo ). The skeleton of L-Mo features a rare truncated rhombic triacontrahedron, which is totally different with the truncated icosahedral K-Mo .
