摘要

A polyoxometalate-silver ethynide composite cluster, [Ag-42(CO3)-{ C = CC(CH3)(3)}(27)(alpha-A-SiW9Nb3O40)(2)](-) (1), demonstrates that we can select the binding site of a polyoxometalate to the silver alkynide cluster by tuning the surface charge of the precursor polyoxometalate. Multidimensional and multinuclear NMR spectra revealed that 1 maintains its precise atomic connectivity in the solution.
