Unsymmetrical surface modification of a heteropolyoxotungstate via in-situ generation of monomeric and dimeric copper(ii) species

Abstract

Unsymmetrical functionalization of a discrete α-{SiW₁₂O₄₀} Keggin with two heterometallic building blocks, a Cu(II) dimer and a Cu(II) monomer, results in the formation of [{Cu₂(O₂CMe)₂(5,5′-dimethyl-2,2′-bipy)₂}{Cu(5,5′-dimethyl-2,2′-bipy)₂}SiW₁₂O₄₀] that displays interesting physical properties.
