In the title compound, poly[μ4-hexa­fluoro­silicato-bis­[aceto­nitrile­silver(I)]], [Ag2(SiF6)(CH3CN)2]n, the Ag atom is bonded to acetonitrile and four F atoms of three different SiF62− ions. The cations are linked via the SiF62− counter-ion by secondary Ag...F inter­actions, leading to a five-coordinated Ag atom.
