Acid-Induced Surface Functionalization of Polyoxometalate by Enclosure in a Polyhedral Silver-Alkynyl Cage
Surface functionalization of polyoxometalate anions with silver(I) tert-butylethynide in an organic solution medium has been achieved for the first time using an acid-induced facile approach. The generated neutral hybrid monomeric complexes [Ag-40(C (CBu)-Bu-t)(22)(CF3COO)(12)(V10O28)]center dot 4CH(3)OH (1) and [Ag-40(C (CBu)-Bu-t)(20)(CF3COO)(12)(Mo6O22)]center dot 2CH(3)OH (2) constitute members of a new silver(I)-polyoxometalate family in which the polyoxometalate anion is embedded in a polyhedral silver(I) cluster assembled by multiple argentophilic Ag center dot center dot center dot Ag interactions.
