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[triple bond]C(t)Bu)(22)(CF(3)COO)(12)(V(10)O(28))].4CH(3)OH (1) and [Ag(40)(C[triple bond]C(t)Bu)(20)(CF(3)COO)(12)(Mo(6)O(22))].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...Ag interactions.
