Assemblies of Increasingly Large Ln-Containing Polyoxoniobates and Intermolecular Aggregation-Disaggregation Interconversions

Rong-Da Lai et al.

Summary: This study demonstrates the first oxalate-assisted lanthanide incorporation strategy for creating rare high-nuclearity Ln-containing polyoxoniobates. A series of high-nuclearity Ln-containing polyoxoniobates have been synthesized, showing an increasingly large structure evolution. Among them, Dy14Nb192 presents the largest heterometallic polyoxoniobate and also the polyoxoniobate with the greatest number of Ln ions reported thus far. Interestingly, both giant Dy14Nb192 and Dy10Nb190 molecules can further undergo single-crystal to single-crystal intermolecular aggregations, forming infinite chains. These new species largely enrich the Ln-containing polyoxoniobate family and offer rare examples for studying structural transformations between giant molecular aggregates and infinitely extended structures at the atomic level.

Three rare-earth incorporating 6-peroxotantalo 4-selenates and catalytic activities for imidation reaction

Weixin Du et al.

Summary: Functionalization with belt lanthanide groups enables the crystallization and structural characterization of homo-metallic selenotantalates. These structures serve as effective precursors for the synthesis of new polyoxometalates with desirable properties like photoluminescence and catalytic activities.

The Dawn of Metal-Oxo Clusters as Artificial Proteases: From Discovery to the Present and Beyond

Francisco de Azambuja et al.

Summary: The selective cleavage of peptide bonds in proteins is crucial in biological and medical sciences, with current applications relying on costly proteases like trypsin. Transition-metal complexes, providing larger fragments and complementary information, have emerged as selective artificial proteases. Their selectivity profile is determined by various structural factors, offering a promising alternative to traditional proteases.

Deliberate Construction of Polyoxoniobates Exploiting the Carbonate Ligand

Mehran Amiri et al.

Summary: Polyoxometalates are molecular metal oxides that can be isolated without capping ligands, showing high negative charge. Carbonate can reassemble with highly reactive decaniobate to form new structures with strong interactions.

State-of-the-art advances in the structural diversities and catalytic applications of polyoxoniobate-based materials

Hai-Yan Zhao et al.

Summary: Polyoxoniobates (PONbs) are a remarkable category of metal-oxo cluster materials that have attracted significant attention due to their structural diversity and high nucleophilicity. In the past several decades, a systematic summary of typical PONbs has been provided, including isopolyoxoniobates, heteropolyoxoniobates, transition-metal-containing PONbs, rare-earth-containing PONbs, and transition-metal-rare-earth-containing PONbs. These studies offer instructive guidance for the further discovery and development of efficient and robust PONb-based functional materials in the future.
