TL;DR: In polyoxometalate chemistry, a large variety of compounds, clusters and solid-state structures can be formed by linking together metal-oxygen building blocks as discussed by the authors, resulting for instance in the high-yield synthesis of inorganic superfullerenes and giant ring-shaped, electron-rich, mixed-valence polyoxomolybdates with nanosized cavities.

TL;DR: Based on symmetry breaking steps under one-pot conditions, simple molybdenum oxide-based building blocks initially assemble to 'giant molecular wheels' in a fast process followed by further slower assembly processes leading stepwise to more complex mesoscopic architectures including spherical ones and finally to those with a size larger than 500 nm.

TL;DR: In this paper, an ion-type stable cluster anion with spherically shaped stable shell was obtained, and the anion 1a exhibited a remarkable overall "onion-type" structure, thereby revealing also a novel type of inclusion: a hydrogen-bonded cluster with 'onion type' structure.

TL;DR: The reaction of an aqueous solution of sodium molybdate with cystine hydrochloride acting as educt and reducing agent at rather low pH values (≈ 1.5) results in the formation of ring-shaped clusters which capture the oxidation product of ======COO−, i.e., the diprotonated cystines at the inner wall of their cavities as mentioned in this paper.

TL;DR: In this paper, stable functional complementary clusters, i.e. of the electrophilic and nucleophilic type, can be added, resulting in the planned formation of the related reaction products: the high-yield synthesis of the crystalline compounds [Me2NH2]10- [{(SiW11O39)Mo3S4(H2O)3(µ-OH)}2]
