An Ag4diamond is encapsulated by silicotungstate ligands in TBA8[Ag4(DMSO)2(γ-H2SiW10O36)2]⋅2 DMSO⋅2 H2O (Ag4; DMSO=dimethyl sulfoxide, TBA=tetra-n-butylammonium), which was obtained by reaction of TBA4H4[γ-SiW10O36] with AgOAc in an organic medium. Polyoxometalate Ag4 (see picture) selectively catalyzes hydrolytic oxidation of various silanes to the corresponding silanols in high yields (72–96 %).
