Three Double-Layered {Ni₈}@{B_n}₂ (n = 3, 4, 6) Cluster Sandwiched Polyoxometalates

Two Different Three-Dimensional Uranium-Containing Polymolybdates Based on Zn(II) for the Heterogeneous Catalytic Construction of C–N Bond

“…Polyoxometalates (POMs) are one of the most representative classes of metal–oxo cluster compounds with diverse architectures and properties. , Extensive concerns have been aroused not only due to their fascinating structural aesthetics but also they provide possibilities for understanding the relationships between structures and properties from microscale to macroscale. − One advantage of POMs is their artificially controllable compositions, which gives us a powerful tool to investigate the influences of architectures on properties including the skeleton metals, heteroatoms, heterometals, and so on. , Abundant transition metals (TMs) can be incorporated into the structural design, leading to a wide range of TM-containing POMs with remarkable properties and applications. − Among them, the Keggin-type, Dawson-type, and Anderson-type POMs containing TMs have been extensively studied and have shown great potential application in catalysis, medicine, and material fields. − However, the introduction of TMs into Silverton-type POMs, one of the earliest discovered types, has received less exploration throughout the centuries that have transpired. − …”

{SeO2(OH)} Bridging Lanthanide-Containing Antimono-Seleno-Tungstates

“…The exploitations of brand-new cluster-based materials with unexpected structural diversities, immense academic values, and wide applications have long intrigued worldwide research interest and held a significant position in advanced material science. − Polyoxometalates (POMs), a class of nanosized metal-oxo-clusters with an oxygen-rich surface, high negativity, and excellent redox ability, − are persistently activated at the forefront of the cluster category due to their capacity to serve as inorganic polydentate ligands (correlated with high reactivity of the oxygen atoms encircling the vacant sites) to capture functional metal lanthanide (Ln) and transition metal ions. − This combination gives them a variety of structural configurations and demonstrates unique electronic, catalytic, magnetic and optical properties. − …”
