Generation of cluster capsules (I-h) from decomposition products of a smaller cluster (Keggin-T-d) while surviving ones get encapsulated: species with core-shell topology formed by a fundamental symmetry-driven reaction

A novel and fundamental reaction system of matter following a type of 'supramolecular Darwinism' leads to the formation of giant spherical nano-sized cluster capsules as kinetically controlled destination having the highest possible symmetry (I-h) and formed directly from the decomposition products of the well known but less symmetrical Keggin anions (T-d) in aqueous medium in the presence of Fe-III-acting as a type of environmental influence-under conditions where Keggin anions are known to be extremely stable; remarkably the remaining non-decomposed Keggin anions finally get (non-covalently) encapsulated protected by the formed spherical capsules of the new supramolecular compound [PMo12O40 subset of {(MOVI)MO5VI}(12) (Fe30O252)-O-III- (H2O)(102)(MeCO2)(15)]. xH(2)O 1 = 1a . xH(2)O (x approximate to 120).
