A pyrovanadate-templated silver(i)–ethynide cluster circumscribed by macrocyclic polyoxovanadate(v)†
Abstract
In the giant mixed-metal silver(I)–ethynide cluster compound [Bz(Et)3N+]8[(Et)4N+]2[(V2O7)2@Ag44(CCtBu)14@(V32O96)], the cyclic polyoxovanadate {V32O96} located at a site takes a contorted configuration to wrap around an inner Ag44 cluster that in turn encapsulates a pair of pyrovanadate templates.
