Abstract
The construction of pure‐inorganic framework materials with well‐defined design rules and building blocks is challenging. In this work, we show how a polyoxometalate cluster with an integrated pore, based on the [P 8 W 48 O 184 ] 40– (abbreviated as {P 8 W 48 }), can be self‐assembled into an inorganic framework using silver ions which both enable reactions on the cluster, as well as links them together. The {P 8 W 48 } was found to be highly reactive with silver ions resulting in the in‐situ generation of fragments, forming {P 9 W 63 O 235 } and {P 10 W 66 O 251 } in compound ( 1 ) where these two clusters co‐crystallize and are connected into a POMZite framework with 11 Ag + ions as linkers located inside clusters and 10 Ag + linking ions situated between clusters. Decreasing both the concentration of Ag + ions, and the reaction temperature compared to the synthesis of compound ( 1 ), leads to {P 8 W 51 O 196 } in compound 2 where the {P 8 W 48 } clusters are linked to form a new POMZite framework with 9 Ag + ions per formula unit. Further tuning of the reaction conditions yields a cubic porous network compound ( 3 ) where {P 8 W 48 } clusters as cubic sides are joined by 4 Ag + ions to give a cubic array and no Ag + ions were found inside the clusters.
