Abstract:2‐(2‐Amino­eth­yl)pyridine (2‐aep, C7H10N2) acts as a bridging ligand in bis­[μ‐2‐(2‐amino­eth­yl)pyridine‐κ2N:N′]disilver(I) dinitrate, [Ag2(2‐aep)2](NO3)2, and bis­[μ‐2‐(2‐amino­eth­yl)­pyridine‐κ2N:N′]disilver(I) diperchlorate, [Ag2(2‐aep)2](ClO4)2. Both salts contain the dinuclear [Ag2(2‐aep)2]2+ cation, which possesses a crystallographic inversion center. The Ag⋯Ag distance is 3.1163 (5) Å for the nitrate and 3.0923 (3) Å for the perchlorate salt, and may indicate a weak d10d10 inter­action in each case. Essentially linear coordination of the AgI atom is perturbed by weak coordination to the anionic O atoms. These latter inter­actions organize the dinuclear cations into one‐dimensional polymeric chains in the crystals of the two salts.
