2-(2-Aminoethyl)pyridine (2-aep, C7H10N2) acts as a bridging ligand in bis[mu-2-(2-aminoethyl)pyridine-kappa(2)N:N']disilver(I) dinitrate, Ag2(2-aep)22, and bis[mu-2-(2-aminoethyl)pyridine-kappa(2)N:N']disilver(I) diperchlorate, Ag2(2-aep)22. 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) A for the nitrate and 3.0923 (3) A for the perchlorate salt, and may indicate a weak d(10)-d(10) 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.
