Investigating the autocatalytically driven formation of Keggin-based polyoxometalate clusters

Catalytic consequences of composition in polyoxometalate clusters with Keggin structure.

Mechanistic consequences of composition in acid catalysis by polyoxometalate keggin clusters.

The kinetics and mechanism of ether and alkanol cleavage reactions on Brønsted acid catalysts based on polyoxometalate (POM) clusters are described in terms of the identity and dynamics of elementary steps and the stability of the transition states involved. Measured rates and theoretical calculations show that the energies of cationic transition states and intermediates depend on the propertie...

Acetate-driven polyoxometalate demetalation: an open-shell diiron polytungstate comprising two rotational Keggin isomers.

The effect of acetate concentration on the formation of {SiW10Fe2}-based complexes is demonstrated by the synthesis of an open-shell diiron tungstosilicate derivative featuring two rotational Keggin isomer units.

ε-Keggin-based coordination networks: Synthesis, structure and application toward green synthesis of polyoxometalate@graphene hybrids.

Four coordination networks based on the {ε-PMo(V)(8)Mo(VI)(4)O(40)(OH)(4)Zn(4)} Keggin unit (εZn) have been synthesized under hydrothermal conditions. (TBA)(3){PMo(V)(8)Mo(VI)(4)O(36)(OH)(4)Zn(4)}[C(6)H(4)(COO)(2)](2) (ε(isop)(2)) is a 2D material with monomeric εZn units connected via 1,3 benzenedicarboxylate (isop) linkers and tetrabutylammonium (TBA) counter-cations lying between the planes....
