The trinity of polyoxometalates: connecting {M12} Keggin and {M18} Dawson clusters to triangles.
Two topologically equivalent triangular POM aggregates based upon the Keggin () and Dawson () cluster species, with distinctive double {W-O-M} intra-molecular linkages involving Mn(III) and Co(III) ions are presented; both these compounds demonstrate electrocatalytic activity.
متن کاملMonolacunary Keggin polyoxometalates connected to ten 4d or 4f metal atoms.
The rational self-assembly of mono-lacunary Keggin clusters with 4d and 4f metal salts via a conventional method has yielded two novel polyoxometalate-based 4d-4f heterometallic compounds containing lacunary Keggin anions connected to ten metal atoms: {[Ag{Ag2(H2O)4}{Ln(H2O)6}2H ⊂ {SiW11Ln(H2O)4O39}2]·nH2O (Ln = Ce and n = 7 for 1, Ln = Pr and n = 3 for 2). Their structures were determined by s...

متن کاملMolecular interactions between serum albumin proteins and Keggin type polyoxometalates studied using luminescence spectroscopy.
The interaction between the plenary Keggin H3PW12O40, lacunary Keggin K7PW11O39 and the Eu(III)-substituted Keggin K4EuPW11O39 (Eu-Keggin) type polyoxometalates (POMs), and the proteins human and bovine serum albumin (HSA and BSA) was studied using steady state and time-resolved Eu(III) luminescence and tryptophan (Trp) fluorescence spectroscopy. The excitation spectrum of the Eu-Keggin POM is ...
متن کاملMagneto-optical response of 3d-decorated polyoxomolybdates with ε-Keggin structure.
A family of virtually isostructural tetra-capped ε-Keggin-type polyoxomolybdate(V) cluster compounds, [Mo12(V)O28(μ(2)–OH)10(μ(3)–OH)2{M(II)(H2O)3}4]·nH2O ({M4(II)Mo12(V)}, M = Ni, Co), exhibits magnetic-field-dependent optical response in their electronic absorption spectra in the 0–33 T range. On the basis of Effective Hamiltonian Crystal Field calculations, we find that the observed field-in...
