The title compound, [Ag2Mn(CN)4(C10H8N2)]n or Mn(bipy){Ag(CN)2}2 (bipy = 2,2′-bipyridine) is isostructural with Cd(bipy){Au(CN)2}2 [Guo et al. (2009). CrystEngComm, 11, 61–66]. The MnII atom has crystallographically imposed twofold symmetry and a distorted octahedral coordination sphere consisting of six N atoms from one bipyridine ligand and four dicyanoargentate(I) anions, [Ag(CN)2]−, while the AgI atom of the complex anion displays the expected linear geometry. Each [Ag(CN)2]− unit connects to two neighbouring [Mn(bipy)]2+ cations to give an threefold interpenetrating quartz-like three-dimensional framework. No directional interactions beyond van der Waals contacts are observed.
