A pyrovanadate-templated silver(I)-ethynide cluster circumscribed by macrocyclic polyoxovanadate(v)

In the giant mixed-metal silver(I)-ethynide cluster compound [Bz(Et)(3)N+](8)[(Et)(4)N+](2)[(V2O7)(2)@Ag-44(C (CBu)-Bu-t)(14)@(V32O96)], the cyclic polyoxovanadate {V32O96} located at a (4) over bar site takes a contorted configuration to wrap around an inner Ag-44 cluster that in turn encapsulates a pair of pyrovanadate templates.
